Do I care? Not really. When I was 16 and heavily under the influence of punk and "a scene" he was the first artist whose show I saw and immediately thought, "This stuff is COOL".
This is why I love Lady Gaga. If freakin' Eminem is giving you an "Are you okay!?" look, you have to be doing something wrong/right. This is Bjork-level craziness, and I think that's super cool.
