Nate Dogg and Warren G - Regulate (instrumental) Em - 95,40 bpm
Notorious B.I.G. - Going Back To Cali (acapella) D#m - 99,06 bpm, one semitone up to Em.
Update, left in the doubles (going going back back to Cali Cali) and left in Nate + Warren.
Better, more relaxed vocal placement (maybe half a beat).
