Ah, yes, I have Endtroducing as well, and it is an amazing album.
In all seriousness, though, it seems like a lot of those bands you posted, like Gorillaz, Dan the Automator and DJ Shadow, are extremely heavy on the electronica hybridization that I wouldn't really call them hip hop anymore, but electronic music with hip hop influences. Gorillaz, in particular, seems more like a "bit of everything" band that occassionally does hip hop really well =). I suspect a few more bands on some of these lists are like this, as well.
A lot of the rest of the artists you mentioned are much older, "classic" figures of hip hop, but I haven't heard very many modern artists mentioned at all.
Also, since when is Eminem good? Have the masses decided that we like him despite the immature, misogynist lyrics now? You'll forgive me if I don't hop on that train =P
It is just very difficult not to get jaded about a genre that seems inundated by talentless knockoffs, y'know?
I'll check out Aesop Rock, and Buck 65 though, a lot of people mentioned them.
