Were do I find some jam along tracks?

Diss diss, where to find? Help me find all the diss tracks out there.

• I'm interested in finding a list of every hip hop/rap diss track out there as the basis for a research project. Where can I find a listing? I've emailed many of the major music services (itunes, emusic, Spotify, Gracenote, etc...), but discovered that such lists do not seem to be retained because diss tracks do not form a coherent genre by themselves. Is there a compendium/some kind of official list of diss tracks? The alternative would be to hunt down the meanings of lyrics of all hip hop/rap artists (or look up each song on youtube to see if a song is labelled with the word 'diss'), but I want to exhaust the possibilities of finding an official list somewhere. I have run the obligatory google search, but it turns up unofficial lists, and wonder about the completeness/quality of those. Any leads would be appreciated!

• Answer:

  This would be a long list. Diss tracks are extremely common, to the point that almost every rap album has one or two of 'em. You might start with the http://en.wikipedia.org/wiki/Beef_(film) documentary series, which will at least point you to some of the major hip hop feuds and the songs they produced.
