Listen to Big Sean, 21 Savage, and Metro Boomin’s new song “Pull Up N Wreck”

The Detroit rapper announced a collaboration with Metro Boomin on Twitter Thursday. But the 21 Savage feature comes as a surprise, as Sean teased fans with just the single's photo art, omitting any mentioning of the Atlanta rapper.

The song follows Big Sean's latest success; last week his fourth studio album "I Decided" was certified platinum, while his 2011, Finally Famous also went platinum, and the 2013 Hall Of Fame went gold on the same day.

A proper way to close out a successful year.
