Too many to choose from

I like that you like Stefy too. I don't think too many people know who they are and I definitely see why you put them at #1.

They are really cool, Chelsea is probably the best cathiest tune ever created, it just want to make you dance, sing and become hyper in a good way

I think Stefy got a lot of publicity and spotlight with that JTMD movie. Their album didn't do too bad for a new band either.
