Why didn't anybody tell me about this site?
 

My sister just recomended me legalsounds.com. All I got to see is DAYUM!!!! MP3 dirt cheaps yow. I like my EDM and they got everything that I use to buy at like $4, now buy em at $.09. My DJ sets will get even more interesting!!!

Never knew about it before.

Warning, it's Russian, the legality is probably questionable at best in the US, although the likelihood YOU would be prosecuted is low, they're almost certainly violating copyright laws here, and there are complaints online about the quality of some of the songs as apparently they are rips. Also a few comments about $$ disappearing into the ether.

Caveat Emptor.
