If you want to know the best bands, albums and songs of 2007, you don't need to ask a journalist any more. They'll just say Arcade Fire or Radiohead, in any case. No, what you want to do is ask more than 600 MP3 bloggers, since they're the new online tastemakers deciding what's hot and what's not in the music world.

Which is exactly what MP3 blog aggregator Hype Machine has done. It's been rooting through the archives of more than 600 blogs to produce definitive lists of the top 50 bands, albums and songs of 2007. The top band is, er, Arcade Fire, and the top album is, ahem, Radiohead's 'In Rainbows'. Okay, so maybe the bloggers aren't so different from the journalists.
