Brandy released the lead single from her new album "Two Eleven", due in May. The employs techniques used on R&B and Hip-Hop songs as of late--auto tune, rapid repetition, and other vocal manipulation techniques like stuttering and deepening of the voice. Chris Brown provides a rap in the bridge, different from how most would expect to hear him on a record.
The song isn't necessarily a club song but it can generate a nice dance video if need be. Chris could definitely have a routine in the video and it wouldn't be out of place. "Put It Down" doesn't sound much like what is on the radio as far as the instrumental is concerned but the repetition should make it good radio fare.
