Though their collaborative musical output has been scarce, Lil Wayne and Dr. Dre have an arsenal of tracks in the can. During an interview with MTV News, Weezy revealed that he’s recorded “probably like 90 songs” for the West Coast veteran but that he’s unsure which tracks will ever be released.

“I’ve always worked with Dre,” he said. “I’m not sure if you guys know how Dre works, Dre always send you a song, so I done probably did like 90 songs for Dre. You just never know which one he gonna put out.”

Wayne, who is working with Dre on his own line of Beats By Dre headphones, says that he’s always open to collaborating with Dre. “I’ll always be up to work with Dre, it’s always cool with him,” he said. “As far as the headphones, I’m super excited about that collaboration, I couldn’t be more excited.”
