In a short amount of time, Wiz Khalifa has become a mainstream hip-hop success story, mainly with hometown anthem "Black and Yellow" entering the upper reaches of the Billboard Hot 100. With follow-up single "Roll Up," the Pittsburgh rapper is attempting to show his range by taking it from the stadium to matters of the heart. "Whenever you need me, whenever you want me/You know you can call me, I'll be there shortly," Khalifa confesses over synths and drums to his love interest, who finds herself cheating on her significant other with the MC. Not only does he like his lady friend romantically, the rapper also offers his unconditional friendship, saying, "I could be your best friend, you could be my homie." While "Roll Up" is a noticeable change from Wiz Khalifa's previous releases, the tune's laid-back emotional vibe is an appreciated left turn.
