I love Lady Gaga.
She's good, her album topped the US Charts and sold more than one million copies in its first week. 
That is not surprising at all.
No it's not, and she studied at CAP21 but ended up dropping out to become a professional musician?
That was obviously a good decision on her part.
She obviously didn't need to stay there or she might be stuck doing Off- Broadway productions that they train for. 
I cannot imagine her on broadway.
I can't either especially since it's much more of a tourist destination.
