It was revealed in the teaser for Eminem’s Kamikaze part 3 interview that there was a track on the album that Dre had to pull because he felt the track “went too far.”
“There’s a couple of songs that he kind of dated them just because he didn’t have a good reaction to him and he also felt like one of them was going a little far. It definitely went way too far.”
It will be interesting to see exactly what “too far” to Eminem is. Hopefully he will touch base more on that track when part 3 comes out.
