hip young player with dreads bouncing in his car

was listening to a song that had a lyric that went "i been (waiting)" (?) and had a beat somewhere between dancehall, r&b and the weeknd. not dubsteppy per se and def not house or actual r&b.

any ideas?

yeah I believe that's Grim Reapah

btw on a lark I just did a search for "brbrbrbrbr grim" and happened to type the right amount of brs to hit a whiney post
