Ask HN: Your thoughts on my idea for youtube based song discovery?

Hi, When I need to look for some nice music I usually go to YouTube and type two or more songs in the search and then look for playlists which have both my songs. It sometimes even work with 3 or more songs+ matching one playlist. And almost always the playlist with less than 20 songs have other songs which I really like. So anyway, I was wondering if this thing can be automated.. Where say you type in two songs, then the program searches YouTube playlists which have both (or all in case 2+) songs and then starts playing them. You can vote a song up if you like the recommendation. This increase the number of song searches, henceforth the permutations to find more playlists with other nice songs. OTOH with each dislike you have more filters. I have been searching for songs like this for sometime now with good success. So, what do you guys think of this?
