Top Songs of 2009 by The Hype Machine
This list of top songs of 2009 was compiled by users of The Hype Machine which aggregates info from music blogs. I haven’t sampled all the songs, but they look like dance music or mashups. Even better, you can listen to the songs online then buy them from iTunes or Amazon.
Oh wait, after listening to a few songs, I was asked to sign up for a free account to keep listening to the music. Not a bad tradeoff.
