sounds like ...

David Guetta's new song, "Hey Mama," featuring Nicki Minaj, Bebe Rexha, and Afrojack sounds a bit reminiscent of Rihanna. But whatever they're doing, it's working. It's great, and fun to listen to.

favorite song friday: jessie j's bang bang

Pop music production has become so systematic. Jessie J, who appeared during awards season on a Fashion Police show with Joan Rivers told the group how her song, "Bang Bang," was created. She wrote it and recorded it, and then the producer brought in Ariana Grande and Nicki Minaj to add their parts. Jessie J never even met the other two ladies until the video shoot. And the trio performed the song live for the first time at the recent MTV Video Music Awards. That's how the music biz works these days. While it may not make for a true collaboration, the end result is still a fun song.

Singer/songwriter Jessie J has written songs for Chris Brown ("I Need This"), Miley Cyrus ("Party in the U.S.A."), Britney Spears ("Hold It Against Me"). She can also do a mean cover of other stars' megabits. Here she does a wonderful rendition of Rihanna's "We Found Love."
