Somebody give these people a Grammy.

A recent introduction to the Apple App Store, Acapella by Mixcord, has got everyone producing their own versions of songs in a cappella. And some of them are bang on point to say the least.

Naturally, "Hotline Bling" got the treatment.

She drops this one like it's hot.

This  guy's version of T-Pain's "Buy U A Drank" bangs.

We've heard worse remixes of Kanye's "Power".

This guy even got Missy's vocals on point.

Dude must be an official Hov impersonator...

"Crank That" proves it's still timeless.
