I suddenly feel so much more mainstream reading this thread...!

Top 3 would be:
Snow Patrol - Eyes Open
Kasabian - Velociraptor!
The Black Keys - Brothers.

And in addition, if I'm in that mood...
Civil Twilight - Civil Twilight.

Alanis Morisstte - Jagged Little Pill

Linkin Park - Meteora

EMPRA - Empra

Crowded House - Recurring Dream (has come very close to making this list for me)
