WowWee Paper Jamz - The Pop Portal Of Doom (Flash Game) Gameplay

I've been really invested in these things lately, considering they were what got me into rock music, so here's this. Is it just me, or does the Justin Bieber Keytar contrast with this game? I know pop rock is a music genre, but if WowWee meant for Paper Jamz to be against pop music, why would they make a Justin Bieber keytar?
