The first m-flo song I'd heard was m-flo loves Boa's Love Bug. Very cute pop song. Their collaborations always contain polite (like Will Smith), fun rap with sweet singing.

m-flo's new album is Cosmicolor which features a lot of pop singers that I find easy to listen to including Crystal Kay, Bonnie Pink and Namie Amuro. I don't know much about m-flo, but this album centers around galactic, cosmic, spacey sounds. There's also a track, Love Long & Prosper by m-flo Loves Star Trek. It also highlights a variety of singers including a Korean singer(Alex from Clazziquai Project), a Chinese singer(Edison Chen) & a Thai rapper(Thaitanium).
Definitely, the album contains some enjoyable songs though it does get a bit repetitious after sooo many tracks. Their new PV is from track 2, which feature Crystal Kay, Love Don't Cry. ~6/10 rating~ dl?
