Waze last month offered up Shaq’s voice as their free celebrity download, in time for the NBA Playoffs, and now for the month of May, the next free voice download is T-Pain—which means every single direction is spoken with autotune.

How to add T-Pain to Waze? Launch Waze for iOS, then go to:

Menu > Settings > Sound > Voice Language > T-Pain

While it may be neat to hear T-Pain autotune all of your directions, it may get annoying after a while. Just make sure you don’t let him buy you a drink while you’re driving.
