New Biebs music of the mixtape sort!

Justin Bieber and rapper Tyga teamed up for the butter smooth, laid back track 'Wait a Minute,' which will be featured on DJ Tay James' upcoming 'We Know the DJ Radio Vol. 3' mixtape.

In 'Wait a Minute,' The Biebs continues to show off his vocal evolution, as he delivers his verses in a smooth, R&B style, while Tyga spits his rhymes over fingersnaps.

When Tyga starts rapid-firing his raps, lookout! it's pretty awesome.

Ultimately, Biebs and Tyga present themselves as a vocal yin and yang, since the two gentlemen have totally different yet complimentary styles.

The fade out is pretty sweet, too.
