pandora is my new best friend, i got a big list in my notebook now of rappers to go get albums from. some i had heard of but hadnt got around to checking out.
grooveshark is pretty dope too since you can make your own playlists and there aren't commercials and no limitations on how many times you can skip a song
you can listen to stations and whatnot I haven't really fucked with that just the creating playlists stuff. So I guess in that regard pandora is good if you're trying to hear some new shit I just get annoyed with the commercials and not being able to skip.
