I feel like this will be amazing. Em is bringing his best lyrical content in years on this album, and I'd imagine his label and himself would have to feel extremely confident in this song to make it the second single; even if it is Rihanna singing the hook. Two amazing artists can still make a bad song together. This is what's basically going to represent the album to the general public.
This will be a hit.
Rihanna + Eminem alone = HIT.
Rihanna's tweet sound very confident. It wouldn't be a 2nd single if they weren't sure it was going to smash.
I'm VERY excited. I hope the Queen debuts a new hair on the video, a la Love the Way You Lie.
#R8 is coming.
