Movie Instrumental Music?

I'm having a debutante ball in a couple of months, I was going to
create a video similar to this, with a different plot.

But the music is REALLY good,  i was wondering if anyone knew the
songs or if not, could recommend some songs similar to these,
especially a song similar to the one that starts at 1:25
thanks for your help.
