Miley: 300k
Jonas Brothers: 350k
Miley 300k, because it seems like her little fans will still be unsure of who she really is.

JB 350k because their 2nd album is almost at 2 million, and still on the chart since it's debut. Just seem like their real fanbase is their.
I'm surprised, but I love all the Jonas Brothers songs.

Except for "Mandy" and "Kids of The Future". Other than that, I can't deny they have catchy, yet corny, songs.
As for music135, "Burnin Up" is like their first song to get like major Pop radio support, whether it be real or payola, LMAO. I'm sure if it wasn't for that, it'd be peaking top 20/25 like their other songs.
