I have a top 5 and a second 5, no particular subordering in each group. In my opinion, it was a very good year in music.
Spoon: Ga Ga Ga Ga Ga (Britt Daniel does more with less than anyone since John Cage)
Sunset Rubdown: Random Spirit Lover (Over the top madness. essential)
Black Cab: Jesus East (hard to find Aussie psycho-drone. try parasol.com)
The National: Boxer (I slept on these guys for years. they are the real deal)
Seabear: The Ghost that Carried us Away (lovely, simple and fun)
Okkervil River: The Stage Names
Deerhoof: Friend Opportunity
LCD Soundsystem: The Sound of Silver
Bill Callahan: Woke on a Whale Heart
Honorable Mentions: Blonde Redhead: 33, Jens Lekman: Night Falls Over Kortadala, Les Savy Fav: Let's Stay Friends, Panda Bear: Person Pitch.
Disappointments: Arcade Fire: Neon Bible (guess they were one album wonders), Band of Horses: Cease to Begin (ditto), Clap Your Hands Say Yeah: Some Loud Thunder (ditto ditto), Liars: Liars (this just plain sucks), Modest Mouse: We were Dead before the Ship Even Sank (ditto).
