It's tough to number all of these because if I had a choice, I'd just label all 1A, 1B, 1C, etc. However, in fairness to the thread:
Purple
Tiny Music
Shangri-La Dee Da
No. 4
Core
It's an absolute shame that the band has only released five albums to this point. Let's hope they make up for this. At least there isn't an atrocious album in the bunch though.
