I like Wonderful World as a song, the main detraction is that it's being released by
J=J, instead of, say ANGERME. I wanted the J=J brass to last forever.
The PV is simple, but not bad at all. Karin looks so enthusiastic and into the lyrics!
I'm still looking forward to
Ça va, as well. It's not brassy, but it has the potential to be a little... edgier? than WW is, at least. ^^
