Rihanna has chosen the fun pop track "You Da One" as the official second single from her sixth studio album "Talk That Talk" (November 21st, 2011) - Produced by Dr Luke, and written by Ester Dean, "You Da One" has lots of typical Riri island flavor, sassiness, a hot production (the dubstep breakdown!), and lyrics that will get stuck in your head 'til the end of time. This has 'smash hit' written all over it.
