Oddly enough most of my new music comes from
Download mp3 music from megaboon.com
I just see albums that look good or have interesting covers or titles, play a sample and if I like them then I buy them. Some music from here of course, then the rest of it would be accidentally, like if I hear it on the TV or in a movie perhaps. I don't actually go out looking for new music (other than the above) as I have already way too much to really ever listen to.
