Carnavas by Silversun Pickups -- This came out last year, and I put on my list last year as well. I listened to it even more this year though.
The Boxer by The National -- This is probably my favorite music to listen to while programming or writing. The only problem is that the songs can be so engrossing that it can be distracting.
Neon Bible by Arcade Fire -- If somebody told me "there's been no good music in 2007" my retort would begin with Neon Bible.
Because of the Times by Kings of Leon -- The consensus criticism of this album is that it was too fractured and all over the place. Maybe that's true, but the songs are excellent. Put this whole album on your iPod and hit shuffle. Every time one of the tracks comes up, it's an instant joy.
In Rainbows by Radiohead -- This is a great album -- also a good retort to any "2007 sucked" claims. I have a feeling that it will remain in heavy rotation for me next year.
Ga Ga Ga Ga Ga Ga by Spoon -- This is another enjoyable album by Spoon. This is one of those albums where each time I listen to it I ask myself "why don't I listen to this more often?"
Robbers & Cowards by Cold War Kids -- I think this also was a 2006 album, but I didn't hear it until this year. A very good album overall, but I especially love "Hang Me Out to Dry."
Icky Thump by The White Stripes -- This was a disappointing album to some people. To me it is a great listen, even though it is probably not as memorable as previous albums by The White Stripes.
Graduation by Kanye West -- I go through love/hate cycles with this album. I tend to listen to it way too much, get sick of it, then two weeks later start all over. This definitely has some weaknesses, but there are too many good tracks to ignore it.
