It’s official: this week’s Billboard album sales chart has Kanye West’s “Graduation” in first place, selling a stunning 957,000 copies in its debut week and in the process scoring the 15th highest weekly sales total since 1991 and the biggest debut of the year. As we all know, 50 Cent had threatened to retire if his own “Curtis” failed to outsell Kanye (it didn’t, coming in second with 691,000 units sold). No word yet out of his camp as to 50’s next move, but we recommend golf.

One of the last remaining big-name holdouts (along with the Beatles) to making their songs available digitally, Radiohead has finally committed to selling their back catalog online–sort of. The bad news: consumers will only be able to purchase entire albums, rather than individual tracks; in addition, the albums will not be sold through iTunes (and in fact will only be sold through UK website 7digital.com). The good news: US buyers can indeed purchase the Radiohead material from 7digital (at about $14 per album), and the tracks are being sold as DRM-free MP3 files.

Speaking of downloading music, perhaps illegal downloading wouldn’t be so prevalent if legal downloading weren’t so undesirable. Case in point: the new website SpiralFrog.com, which launched Monday. While all downloads on the Universal Music Group-sanctioned site are technically free, users must jump through numerous hoops in order to obtain and listen to the songs. To download songs, users must sit through advertising (the source of the site’s revenue). To prevent their songs from being locked up, users must complete a detailed registration form and login at least once each month. In addition, downloaded tracks cannot be burned onto a CD or transferred to an iPod. And did we mention it’s not compatible with Macs at all?
