Legal music downloading... Free?

So I found this completely awesome website in Rolling Stone magazine, www.spiralfrog.com and it is a legal downloading place that has signed with some major and independent record labels. And the best part? Completely free. The only way this works is that the website is supported by ads, the person downloading (each download is 90 seconds) is forced to stare at the downloads, the record companies get paid w/ money from the ads. It's amazing. There is a downfall or two though: You can't burn this music onto CDs, you can only put it on mp3 players. Also, the music is not supported by Apple, so it won't play on an ipod. But it's awesome for the other people, like myself, who are too poor for an ipod. I'm pumped. The site is supposed to be operational later this month. Woot.
