Don Toliver was a surprise feature on Eminem's surprise album Music To Be Murdered By.

Don Toliver did the chorus for the D.A. Doman produced Track "No Regrets." He explained how that went down in an interview with Ebro.

"That's one for the OGs," Toliver said. "He sent it ... I was in the Cactus Jack studio [when I got the call] and I was recording. Flipped that on, did that quick. I think Em was already on tip with what I had going on/  But who really I think plugged the spot was D.A. Doman. No cap.  He was hitting me up like "Me and Em are here right now.'"

According to Toliver, he did his part in about an hour.  Then Em dropped the album a day or two later.
