Eminem weighs in on the best rapper of all-time debate.

Following the release of Music to Be Murdered By – Side B (Deluxe Edition), Em sat down with Zane Lowe of Apple Music to discuss hip-hop. During the conversation, which aired on Wednesday (Dec. 30), Slim Shady explained his opinion on the best rappers of all-time debate.

"Hip-hop's went through too many different transitions for anyone really to be the best rapper of all-time," Eminem told Lowe around the 20:40 minute mark of the interview. "It's evolved. Now people are doing things with flows that I never could have seen happening. But at the same time, rappers from that era meant so much more to that era, just because there were so many innovators and there were so many rappers."

Elsewhere in the chat, Eminem named Lil Wayne, J. Cole, Kendrick Lamar his current favorite rappers and explained how they "rap to be the best rapper."

The Detroit native has more than two decades in the game and has been the subject of much talk. His venomous fast-paced verses have landed him a spot in history books as one of the greats, but such talk is often up for debate.

Eminem's statement comes after the deluxe edition of his latest LP took aim at Snoop Dogg on the song "Zeus." Em presumably went in on Snoop after the Doggy Style rapper's comments about Eminem not landing in his personal top five. While the reasoning behind the firey comments were never addressed, Eminem has never back-peddled his statements.
