what is the tune on the tv advert for flat tv's with millions of bouncing balls?

Answer 1

The artist is José González. It was his interpretation of 'Heartbeats' - originally performed by the Swedish band, The Knife.

It was done for Sony's Bravia flatscreen tele.

Here's a link from the makers of the commercial:

Btw, it was "only" 250,000 balls. :p
