This is a song I've loved for a long time and I've heard it on adverts, TV and films but never managed to find out what it is. You will probably recognise it. I've spent hours trawling YouTube and mp3 sites for info but no luck. I've taken the audio from a skateboard video set in Brazil so I'm pretty sure it's a Brazilian track. There's some skate noise in the clip but you can easily hear the track.

I would be eternally grateful if someone can ID it.

Sorry about the sendspace link, it wouldn't let me attach the mp3 for some reason.
