Here's mine.  It ended up being a top 21, thanks to the late discovery
of the Arcade Fire album, which proved too good to leave out.

1. The Killers - Hot Fuss
2. The Dears - No cities left
3. Arcade Fire - Funeral
4. Mando Diao - Hurricane Bar
5. Franz Ferdinand - Franz Ferdinand
6. Dogs die in hot cars - Please describe yourself
7. The Secret Machines - Now here is nowhere
8. Air - Talkie Walkie
9. Bill Janovitz and Crown Victoria - Fireworks on TV
10.Graham Coxon - Happiness in magazines
11.Nick Cave - Abattoir blues/lyre of orpheus
12.Goldie Lookin Chain - Greatest Hits
13.Mclusky - The difference between me and you is that I'm not on fire
14.Hope of the states - The lost riots
15.The Streets - A grand don't come for free
16.Golden Virgins - Songs of praise
17.The Walkmen - Bows and arrows
18.Belle and Sebastian - Dear catastrophe waitress
19.Green Day - American idiot
20.Magnus - The body gave you everything
21.Charlotte Hatherley - Grey will fade

Honorable mentions for re-release/compilations:
Super Furry Animals - Songbook, which brings together many of the best
SFA tracks since their first album.  I've always had a soft spot for
the furries, but this compilation served as a timely reminder of their
frequent brilliance and ear for an irresistable hook.

Manic Street Preachers - Holy Bible (10th Anniversary edition). This
was a remastered re-release of the original, powerful and occasionally
harrowing masterpiece from the Welsh (then) quartet. Fantastically,
the re-release also includes an unreleased U.S. mix of the album
which, while softening some of the harsh, bleak pain of the original,
serves to freshen it up and bring some of the previously unheard
nuances forward in the mix.

I haven't included a few albums that other people have put in their
lists (the Cardigans, the Wildhearts, Matthew Sweet's Kimi) because I
entered them last year. This is thanks to what I assume are differing
worldwide release dates.

Cheers,
Matt.
