Big Sean and Chris Brown reunite on “Sellin’ Dreams,” one of the many collaborations off Sean’s new mixtape Detroit. The frequent collaborators find themselves in the middle of a sticky situation involving the women in their lives. “It might be too late for me to learn from my mistakes,” sings Chris on the piano-driven track, produced by Da Internz (“Birthday Cake”). The song also features vocals from CBE/Atlantic Records signee Sevyn.
