For classical releases I thought this was a stunning year, but a mediocre year in a lot of other categories. I do however have a few (non-classical) favorites:
Sikilela, by Amabutho; from South Africa.
In both cases I have trouble distinguishing the album name from the performer name and that is often a good sign of quality for world music.
My Beautiful Dark Twisted Fantasy, by Kanye West.
If you're looking for a fun song to download, beyond the stuff you probably already know, try Gyptian's "Nah Let Go," a joyous reggae song.
Most of this year's Spin picks and the like I found fairly boring.
