So, what's his appeal?

Beats the hell outa me. Guess you've gotta be a twelve-year-old girl to get it.

His songs are catchy, and before he trashed himself up with all those ugly prison tattoos, was a very cute, clean cut teen idol for suburban girls (as in non-threatening).

He has a good voice and some of his songs are catchy or fun.

I dunno. Ask Diddy.
