Oh, I'm a sucker for list-y things like this.
TOP FIVE:
1. TV On The Radio - Return to Cookie Mountain (if you haven't heard it yet, just make an effort... the best description I read of it was "doo-wapocalyptic".... or something like that.... - "Wolf Like Me" was also my favourite track of the year)
2. Pet Shop Boys - Fundamental (not a "return to form" as the cliched critical sheep would have you believe cos they never been away)
3. Hot Chip - The Warning (another band bubbling under on the cusp of making it big, and proof that nerds can be winners)
4. Popjustice 100% Pure Pop Music (various artists) - the cheesiest, oddest, most brilliantly executed compilation created this side of 2ManyDJs (this year's secret guilty pleasure)
5. The Knife - Silent Shout ("We Share Our Mother's Health" is probably #2 in my fav tracks of 2006)
Bubbling under - this year's albums by:
Army of Knives (shock horror - a good Scottish band that isn't obsessed with acoustic/rawk guitars!), Arctic Monkeys (not as great as time goes on - still some awesome tracks here though), Johnny Cash, The Killers, Scissor Sisters (but the last two suffered by just failing to match their fantastic debuts) and - wait for it - Robbie Williams (the most surprising album of the year - just heard it, and thought it very good indeed)
