Song of the week: 'Grindin' by Lil Wayne and Drake

Weezy and Drizzy, who introduced slo-jam single Grindin' on Friday at the launch of their co-headlining Drake vs. Lil Wayne tour, ruminate on the daily grind over a menacing drone of sampled piano and machined beats.

Drake's voice blends seamlessly with Wayne's auto-tuned rap as they alternately boast and whine while name-checking everyone from James Bond to Michael Jackson.

Grindin' is the latest Wayne track expected to appear on his The Carter V album.
