The name of the track I'm looking for begins at 00:39 in the video. I know it's only the first few seconds

I've tried Shazam, Sony Ericsson Track ID, but can't find anything because the clip is so short.

Hopefully someone on here will know the name? Will be really happy if someone can identify it for me? Thank you
