Fresh off the stage at Power 106’s “Valentine’s Crush” concert in L.A., Big Sean liberates his lost verse to Drake and Lil Wayne’s “Used To,” which appears on both Drake’s new mixtape If You’re Reading This It’s Too Late and Weezy’s mixtape Sorry 4 the Wait 2.

Over the WondaGurl-produced beat, Ariana Grande’s boyfriend raps about having a “crush on every girl on Nickelodeon,” salutes Kanye for putting him on (“I’m forever reppin’ foot up on the throne”), and even flips Drake’s Usher U-chain line.

“You was poppin’ back when I was wearing pow chains / Now you’re back at home, how mane?” raps Sean, whose album Dark Sky Paradise drops Feb. 24.
