I counted 80.
This list is retarded. GREEN DAY–DOOKIE AT #193???? Then there’s stuff like Oasis, the Strokes, White Stripes, Alanis Morrissette, and the Red Hot Chili Pepper’s Californication!!
And maybe this is a semantics issue, but an "album" is not a greatest hits collection or an anthology. It’s a set of new songs by one group/person. (I would even consider a live album an album, in a less official way–but more so than a greatest hits comp.)
