The 2nd verse is an exceptionally strong Eminem verse. I think the voice distortion that occurs there is preventing some people from realizing that. Everything from "sometimes I wonder where these thoughts spawn from" to "and I can't conquer it" is extremely, extremely strong rapping.
Don't get me wrong, I'm baffled as to why this one couldn't be replaced by something like Don't Front or Baby (not really, because I know it's for commercial purposes). I'd rather Eminem never started cavorting with pop stars, and I'm even a fan of pop music. I don't think the song fits thematically into the album at all. They should've did this song, along with Survival, on some Refill-style addition to Recovery. That's where these songs fit sonically, not on MMLP2.
However, this isn't some shitty track. This isn't the greatest rapper of all time vomitting out a line as horrendous as "Maybe that's what happens when a TORRRnado meets a VOLLLcano ... walk aWAY THO!" This isn't that.
The hatred for the track is a little overdone, because the 2nd verse is really really sick material.
