Drake’s Beats 1 show OVO Sound Radio returned for its first episode of the new year last night, and it was a big one. A$AP Mob’s Cozy Boys and DJ Mustard both stopped by to share guest mixes, with the former debuting some new A$AP Rocky material and the latter premiering a new collaboration with dirty-minded crooner Ty Dolla $ign, fresh off of his excellent album Free TC and a guest turn on Kanye West’s “Real Friends.” Also featuring frequent collaborator Joe Moses in addition to some high-pitched vocal samples, “Wavy” finds Ty$ feeling “wavy like Beyoncé on a surfboard.” Listen.
