since Lisa left the group, Verbal and Taku decided to do something different and work with all the artists they always wanted to. so they started doing the "m-flo Loves" tracks. I think its great and love to speculate about who they're going to work with next. I've also heard lately that m-flo is looking to stop the collabs and get a permanent vocalist again. I know rumors have been Emi Hinouchi (who is on Taku's record label), Yoshika, and Emyli.
