i get last fm thru my xBox live gold membership. wasn't sure if that would work for you or not. looks like it might have. i've been rocking last fm or a year now while i blow glass and love it. a lot of "bootleg' remixes type stuff you might not hear elsewhere. really opened the door to A LOT of new artists as well. i typed in 'remix' in the search box and it's been pulling up random stuff. from brittany spears to aretha franklin to slayer to dead mouse.
And don't forget, robbing Peter only makes him sore, and you can't do business with a sore Peter.
Matt, call me crazy but I trim to Enya. I'd prefer the Eagles or some others but my neck, shoulders and back get stiff when I trim and Enya is sooooooo soothing.
