New Music: Big Sean's 'Research' Featuring Girlfriend Ariana Grande

A new track off Big Sean's "Dark Sky Paradise" has landed online.
The song called "Research" hit the web on Wednesday, February 18, less than a week before the rapper's third studio effort officially comes out.

The new tune features a guest appearance from Sean's girlfriend Ariana Grande. On it, the Detroit native raps about a girlfriend who constantly stalks him by checking up on his phone and email.

"But you unlockin' my cell like you is a cop/ How you decode all my V-mails, G-mails even P.O. boxes got me P.O.'d/ You saw my emails with CeCe when you wasn't CC'd," he says. Grande emerges later on the track to deliver the hook.
