JB covered Drake's track "Trust Issues".  It's being called a remix although Justin is really just singing the same words as Drake.  Biebs did change some of the lyrical content though to be a bit more friendly and Drake does rap in the song.

Instead of the lyric:  "I'mma sip until I feel it, I'mma smoke it till it's done" . . . Justin sings, quote, "I'mma sing until I feel it, I'mma go till it's done."  And later in the track, Justin replaced "B-words" with "women."

Warning, Justin cleaned up his portion of the song but Drake's part has got some language that may not be appropriate for work or young kids.

Here is the new song -
