Characters Singing...?

While listening to music, I got to thinking that some songs I could imagine my characters singing for the heck of it... xD

So, which songs could you imagine them singing? (Note: Not saying that it works for them; to their personality, what would they sing?) If it's not their personality to sing, then I wouldn't suggest this thread...

The past 'acquaintance' of Zentaal would sing this to piss him off. xDDD ALWAYSSSSS. I WANT TO BE WITH YOUUUUUUU, AND MAKE BELIEVE WITH YOUUUUUU. >
And let's not forget Manboy.

Lily: Collide

I think most of the rest are hummers. I can't imagine them singing real words... Dx
