Trust me, I've thought about this a lot:

U2: Achtung Baby
Pet Shop Boys: Discography (Yes, its a greatest hits, whatever, it might be the most brilliant greatest hits package ever).
Billy Bragg: Workers Playtime
Beta Band: Three EPs
Matthew Sweet: Girlfriend
Catherine Wheel: Ferment
Built to Spill: Perfect From Now On

Sorry, my list got long. Now, if only I had time to write that book ...
