I think so. I'm not too sure if they mentioned it somewhere before, though, but i think they listen to western music.

But i dunno if they know U2. Maybe they do, but i dunno if they are fans....but if there's anyone among them who'd listen to western music, it'd be Sho and MatsuJun. (Jun once said he listens a LOT to Beatles....)

you're forgiven. I can have my bouts of fever, too. haha!
