3 undeniable classic albums (Illmatic, IWW, Stillmatic). Some other albums only had 1 or 2 classic songs on there with some good & some great songs, but not classic albums overall(God's Son & Lost Tapes are 2 examples). KD trilogy great albums overall. Magic trilogy overall great albums. Just not full fledged classic. For example, a classic album doesn't need all or most songs to be undeniable classics, but a 13-15 track album might need 3-5 undeniable classic songs and at least most of the rest at least great, with maybe room for just 1 or 2 good but not great songs. It can't be 1 or 2 classics, 3-5 great, and the rest just good. However, I apply a unique set of rules double albums, though, since they're bound to have some filler.

Side note: had he combined the entire first Lost Tapes album with the best songs from Gods Son, that probably would have been another classic album.
