Next month, Grammy award-winning a cappella group Pentatonix will release their eponymous debut studio album. The project is anchored by their incredibly smooth single, "Can't Sleep Love," which receives a sweet upgrade today thanks to Chicago rapper Tink.

"We have become a huge fan of Tink recently because her style and vibe is so so hot, so she's the first person we thought of when we decided we wanted a feature," Scott Hoying of Pentatonix told us of the collaboration. "When we heard her verse for the first time, we were freaking out. She KILLED it.”

We're inclined to agree as Tink rolls through near the end of the video and delivers a verse that's as melodic as it is dope. She plays up the love angle in her own clever way ("You wanna taste you better be bringing more to the table"), and flexes her vocals to the point that she could be the honorary sixth member of the group. At the very least, Tink's inclusion gives this already infectious single more juice.

The Tink-assisted version of "Can't Sleep Love" comes free when you pre-order the deluxe edition of Pentatonix's upcoming album, which is due out Oct. 16.
