Beware of the rapping, though. It's supposed to sound bad and druggy. It's not on all of the songs, thankfully. Although, I kind of like it. watch their music videos, too. quite a trip.
Nice! I think thats how a few of my mate do it too. I mean, thats what Last.fm is for really - helping you get into more artists you might like through song recommendation etc. Its a great idea. I too have recently got into to some obscure/unknown bands & musicians through this. You'll never know what gems you might find.
