Dear God, that's a tough question!
Well, there are a few, I'll probably edit more in later as I remember them, but here are the ones off the top of my head:
Porcupine Tree - 'The Start of Something Beautiful' (anything off Deadwing, really... album of the year IMO)
Strapping Young Lad - 'Love?'/'Skeksis' (both awesome, 2nd best album of the year...although I listen to it more then Deadwing))
Kaiser Chiefs - 'I Predict A Riot' (technically last year, but reissued twice this year)
Elbow - 'Forget Myself'
Opeth - 'Ghost Of Perdition'
Bright Eyes - 'First Day Of My Life'
Cradle Of Filth - 'Nemesis'
Paradise Lost - 'Shine'
Editors - 'Bullets'
Pelican - 'Sirius'
Arcade Fire - 'Rebellion (Lies)'/'Wake Up
Trivium - 'Like Light To Flies'
LOTS more.
