Need Help Identifying Music in a video

Hello Everyone!

I need help identifying music in this video:

http://www.youtube.com/watch?v=vgxDUhRvxTU

First Music: starts at 0:50 of the video (fast catchy tune)
Second Music: starts at 1:19 of the video (flute or piccolo seem to be played; possibly a rendition of a classical music)

Thank you very much!

Most of them are brazilian music but I don't know the names

you can have an idea watching this videos
You can search for forró, xaxado and axé too
