where to download music?

i just bought a Sandisk sansa e260, 4gig. It came with a thing to subscribe to rhapsody and download form there. I go to do that, and the first thing i need is xp, which i exspected, but anyway, then i look at the info, and i need to live in the US to get music. I'm like wtf, where do i get it from now. Then it says, where i can get stuff in Canada, but its a crappy ass deal, like $15 a month for 10 songs. Anyway, this player won't let me use any music i downloaded off limewire because its got some protection shit, so i need somewhere i can download legal songs, and with a good database. i thought itunes would be bad, but at least i coulda got that here. Anyway if you can help please do. :?
