This is a cool project! What's the formula for figuring out if something will blend well (as a human)? I failed several times... The closest I got was "Dreams Nation Army" (Sweat Dreams & Seven Nation Army) https://rave.dj/bS7DTzUs_kvFMQ https://rave.dj/bS7DTzUs_kvFMQ - Sounds okay.

Key and Tempo are (I think, I am far from expert / novice even) the 2 most important points to consider. Most songs wont match so its required to pitch shift to align keys (which can also affect the tempo), and tempo because you want the beats to match up, otherwise it will sound like a mess. Your "Dreams Nation Army" works well because 7 nation army is pretty much a copy of Sweet dreams and they fit well together. VirtualDJ [0] allows to load multiple mp3's and can match key / tempo at the click of a button (manually or autodetect). They even built in the option to split stems using the spleeter tech [1] [0] - https://www.virtualdj.com/ https://www.virtualdj.com/ - if you want to use the spleeter tech, Win 10 is required. It can run in a VM though ;-) [1] - https://news.ycombinator.com/item?id=21431071 https://news.ycombinator.com/item?id=21431071

for djing we can use the circle of fifths and the software “mixed in key” as a starting point: https://en.m.wikipedia.org/wiki/Circle_of_fifths https://en.m.wikipedia.org/wiki/Circle_of_fifths https://en.m.wikipedia.org/wiki/Mixed_In_Key https://en.m.wikipedia.org/wiki/Mixed_In_Key and by adding beatmatching we get very nice mixes or transitions. after a while you won’t need either of these as things will start working out by themselves.

  Just a quick note... Mixed in Key is no longer necessary as both Pioneer and Serato's DJ apps include this functionality in the base, free versions. Also, GP might want to look up the 'camelot system', which relabels keys in a simple numeric system which makes it a lot easier to determine which keys are compatible without memorizing the entire circle of fifths. Every DJ I have met or played with that keymatches labels their tracks in this fashion. You can print this out and stick it on your wall for quick reference: https://mixedinkey.com/wp-content/uploads/2018/03/CamelotWheel.jpg https://mixedinkey.com/wp-content/uploads/2018/03/CamelotWhe...

    > Just a quick note... Mixed in Key is no longer necessary as both Pioneer and Serato's DJ apps include this functionality in the base, free versions. At least in Rekordbox (Pioneer), Mixed in Key is the only way to display both the actual key and the Camelot notation. This is useful for knowing which songs can be easily brought in sync using key/pitch adjustments in software. For example, 9A and 3A are not necessarily easy to mix together, but if you know that 9A is Em and 3A is B♭m, it's only a single half-step adjustment in Rekordbox to make the latter 10A, which is usually easy to mix into 9A. Mixed in Key and the other tools that they provide can also do more than just identifying the key of a song. I wouldn't say it's essential for a beginner, but it justifies its price for someone who uses it professionally or even semi-professionally.

      Actually you hit on one of the lesser-known rules of Camelot system, that +/-7 (aka perfect 5th[edit, this is not right see below]) is mixable, though at a higher danger of clashing. Same with +/-3, at even higher risk. When I read about this the lesson was to do your transitions quickly. This applies to track mixing as a DJ, not sure how mash-up mixes change things.

        > Actually you hit on one of the lesser-known rules of Camelot system, that +/-7 (aka perfect 5th) Er, what? A perfect fifth is +/-1. That's why it's called the Circle of Fifths. +/-7 is a minor second. 9A and 2A only contain two notes in common - the other five will all clash. It's not really mixable in most cases without using special tricks.

        Ah, that's right, I had my wires crossed. The chart I made got lost in a move.... +/-7 is still mixable, as is +/- 3 (not 2). Just gotta be quick. https://www.bestdjgear.net/camelot-wheel-tricks-to-advance-your-dj-skills/ https://www.bestdjgear.net/camelot-wheel-tricks-to-advance-y...
