Personally to me, these methods of finding music don't work. I believe it's because most people tend to listen to music in a genre. Because the above method doesn't work, I have done correlations between different artists I like and the music recommended for that artist. (Example Arists A: Similar B C D; Artists E: Similar C D, then it would recommend C=4 point, D=4 points, B=2 point) This method sort of works, but it mainly yields music I find 'acceptable' not music I find good. Music should IMO be recommended using genre/tags(artists, year, ...) as well as: (rather long list:) tempo, complexity of the music, instruments, amount of instruments, how monotone or varied to music is, then there is music that uses notes to keep you in short suspense and others in long suspense, general sound of the music (rock would be 'rough' while violin would generally be 'smooth'), music patterns, music pattern genre, ... And then you need to train a small neural net per person to figure out witch of all these features is important to the person you are recommending music to. (Edit: added to list of features to look for in music)

That sort of describes the Pandora approach. Each song has a set of "genes" that describe its tone, musical instrumentation, key signature, time signature, rhythmic syncopation, etc. these genes are then used to find similar music. I've found it to be quite pleasing to discover new music when it's seeded with a relatively uncommon song that I like. For instance, I added "Going Through Changes" by "Army of Me", and its recommendations included songs from bands I'd never heard of and actually enjoyed, like Radford, Red (a Christian band, one, as an atheist, I wouldn't ever have browsed on my own, but ended up really enjoying), Maxeen, Black Lab, and Brand New. Each had "genes" that made their algorithm align them with the seed song. I don't use it much right now - I find myself in a cycle of discovery and then stubborn re-listening of the same four or five albums - but I expect I'll go back to it the next time I'm back in that exploratory mood.

  The idea behind Pandora is neat, but I've unfortunately found its actual dimensions insufficient. It always ends up drifting towards mediocre generic pop crap, no matter how far away I start or how carefully I curate. And it doesn't account well for complexity or mood.

I think that for me the approach in TFA would work, if it was applied to songs rather than artists. There are many artists that have a couple of songs I like and a lot of ones I don't care for. Artist-based recommendations go terribly wrong for me for this reason, I think.

Add vocal to this list: There is a lot of great music I don't listen to because it comes with the performers problems, complaints, and political beliefs attached. Some people don't care but for those of us who do it would be great if there was a filter for spoken words.

While it's common to use things like genre, year, musical characteristics, etc, social dimensions may be at least as valuable. Exanples are artists performeing at the same show, collaborating on a project, maintaining personal friendships, signing to the same record label, moving to another group, etc. Most of the music I've found and enjoyed were through these types of connections.

I think Spotify's "Discover Weekly" playlists get pretty close to this. I really, really look forward to each week's new playlist. I listen to a wide range of genres, and completely agree with you that most discovery tools try to pigeon hole you into one or two. Spotify seems to pick up on other associations. I wonder how much neural net stuff they're doing with their big data.
- SyneRyder 10y ago
  EDIT: Oops, somehow missed that The Verge article on how Discover Weekly works had already been posted! It works on a variation of PageRank, where instead of links on pages, it uses songs in saved playlists. (If you have a playlist with lots of songs similar to someone else's playlist, you might like the songs in their playlist too. If a song is on lots of playlists, it's probably noteworthy, etc.)

  I was going to say the same, Discover Weekly frequently really impresses me with some of its selections and I have discovered some excellent artists through it. I'm into electronic music - not what I would consider really obscure stuff, but certainly not mainstream - and many other recommendation systems seem top lump anything electronic together with mainstream "EDM" etc. (which is nothing like what I enjoy) whereas Discover Weekly makes intelligent recommendations of quite obscure stuff. I assume it uses some combination of social data (e.g. music listened to by people who listen to similar artists as you) and the intelligent classification ability they purchased when acquiring Echo Nest. There was quite a good write up about it - I think it was one of these two: http://www.theverge.com/2015/9/30/9416579/spotify-discover-weekly-online-music-curation-interview http://www.theverge.com/2015/9/30/9416579/spotify-discover-w... or http://qz.com/571007/the-magic-that-makes-spotifys-discover-weekly-playlists-so-damn-good/ http://qz.com/571007/the-magic-that-makes-spotifys-discover-... I just wish it would save my previous weeks' playlists as sometimes I forget to listen to them and then they're gone!

What you're describing is is similar how Allmusic categorises artists (categorised? I haven't used it a lot in the last few years, so I don't know how much it's changed). I used to find most of my new music via it. It was in no way algorithmic - it didn't make suggestions, it was just a case of manually following links (given that part of the pleasure comes from searching and discovering independently, no bad thing). It had genres, mood, influences, influencees, etc at the artist level at least. It would seem that Rovi's API could be better leveraged to provide good suggestions than it currently is, if all that metadata is still being attached (though there are things like Spotify's Discover Weekly that I've found to be surprisingly good which I assume use it). [It would have been even better if that had been expanded to album/song level. As the sibling comment suggests, categorising by subject matter would be very useful for a not-insignificant number of people as well.]

The approach you describe is one of many. Traditional collaborative filtering using matrix factorization will "discover" the features you listed, or other non-intuitive features, from patterns in the data. They don't always need to be listed explicitly, and training individual asymmetric models (like your one NN per person) isn't always ideal. Per person models won't make a lot of sense unless each person has rated a large number of songs, which usually isn't the case. In general, methods like this require an epic amount of data to work well for consumers. The Netflix Prize made a dataset with 110 million ratings available, and that was barely enough to make impressive predictions. The issue here isn't the statistical model being used, but the paucity of training data. If you trained this or any other model on one billion rated songs, the quality of the recommendations could blow your mind. They would however still skew toward the average musical tastes.
- Qantourisc 10y ago
  Ow the NN would be rather small though: like 1 or 3 layer kind. The bulk of the identification has to be done before. Although music patterns could be a problem. And the skew toward the average musical taste is exactly my issue. Finding music is more like playing bingo to me. Disclaimer: I haven't used any note-wordy NN yet, so this might still required a ton of input. But if the NN could start recognizing thinks like for example: likes piano with male singer, but a penalty when it includes a violin in these genres (stupid example) it would IMO be an improvement.

  >Traditional collaborative filtering using matrix factorization will "discover" the features you listed, or other non-intuitive features, from patterns in the data. I don't think that has turned out to be the case. Most people's listening habits follow genre, and just don't have that much latent structure to extract.

I've long wondered about other psychological favtors that come into play as well. I wonder if each time I give a song a thumbs up, say, during radio play, they record features like day of the week, month of the year, season, the weather that day, time of day, maybe a geographic classifier like city/suburb/wilderness. These are all things that could be used to make localized, time dependent and situational recommendations. I like a lot of the 'mood' playlists Spotify offers as well, but I've used players in the past where you have to choose between very similar and highly subjective things like calm vs tranquil to populate a mood based list, and I wonder if features I mentioned could make this a more passive process on the user's part.
- amk_ 10y ago
  I like the Songza (rolled into Google Play Music) themed playlists, eg "It's Tuesday Morning , play something for focusing/working out/spring cleaning". Usually there is something within one of the suggested categories I'll listen to.
huuu 10y ago
Agreed. I think suggestions should be based on mood and emotion. For example if I like 'dark' music I might as well like a song from a techno artist and a classical orchestra. But this can be very complex. What some people find aggressive music others find a little too soft. EDIT: by the way: because of the above I also think a recommendation for a song is better than for a band.
