I can name my top three easily, but after that it won't be in any particular order.

1. Radiohead - OK Computer
2. Pink Floyd - The Wall
3. DJ Shadow - In Tune and On Time

The rest:
Radiohead - The Bends, Kid A, Amnesiac, HTTT
Pink Floyd - Wish You Were Here, Dark Side of the Moon

That's nine, but I can't pick one for the last slot. There's far too many candidates. Those artists listed are my favorites to listen to, and therefore their albums are my favorite. I've got two other Shadow albums, but I can't really pick one, and there's a lot of others in my collection that could just as easily take the slot.
