Why are people under-whelmed?
I was wondering if she could go top 10, let alone #1.
The hype was created by Miley only, the most promo it got was on iTunes and VEVO. She's doing pretty darn GREAT.
When you leave for 3 years, you're not expected to SMASH, you're actually expected to flop because you've been out of sight in music for a while.
She came back, with a different label, an ENTIRELY different song and look and she went #1. That is an amazing thing and it shows that Miley has a solid fanbase.
