Moh: I'm not worried about anything. I don't like seeing that many names, but I'm not so short sighted as to think the song will absolutely be bad because of it or that every song with a handful of composers is horrible.
Western (many Swedish) people work on Johnnys songs all the time. Hamasaki Ayumi has a lot of them, too. Can't say I'm excited, but here's hoping it'll sound good.
