As fans patiently wait for Big Sean to drop his next project, the Detroit native liberates a lost verse from Drake and Lil Wayne’s song, "Used To."

According to Miss Info, the song first appeared on Weezy’s Sorry 4 the Wait 2 mixtape, then Drake dropped a new version on his surprise album, If You’re Reading This It’s Too Late.

The WondaGurl-producer banger features a slinky beat and sinister keyboards. On the song, Sean Don spits a blistering verse about haters testing his patience and why he’s at the top of his game.

“F--- every OG that passed up on my and put me on a song / Except for ‘Ye so I'm forever reppin’ foot up on the throne,” he raps, adding, “Album on the way / Rapping like I got a baby on the way / I'm like Baby with the pay / Pay me when a day.”

Meanwhile, Big Sean is keeping himself busy during the NBA All-Star Weekend in New York. The “Blessings” rapper recently performed with his mentor Kanye West at the first annual Roc City Classic concert. Sean, alongside Pusha T and 2 Chainz rapped “Mercy” and “Clique.” Then Yeezus assisted Sean with a rousing version “IDFWU.”

As for the album, Sean plans to release his third opus Dark Sky Paradise on Feb. 24.
