I'm also curious if any one of them also listen to bands like ONE OK ROCK, or UPLIFT SPICE (local). The only thing I remember hearing them say about American bands is listening to The Jonas Brothers (Haru) and Red Hot Chilli Peppers (Tomo) in the AM2 panel interview. I didn't get Mami's and Rina's.
PS: I really have to say this... SCANDAL x UPLIFT SPICE = I don't event wanna say it.
Tomo on bass/vocs, Chiori on vocs, Mami & U-Key on guitars, and Tobita on drums, a Super-group on a collaborative effort for an anime OST or something. That'd be the day. Oh yeah!
