We caught up with celebrity DJ (and Beyoncé's little sister!) Solange Knowles at the launch of Carrera's new 6000 sunglasses in New York, where the mix master gave us the scoop on her favorite summer jams. "It changes all the time," Knowles said. "But right now I'm loving "Million Dollar Bill" by Whitney Houston, and a Miguel song called "Adorn." We're adding both to our summer playlist! One more reason to listen to Solange's picks: Today is her 26th birthday!
