Trying to remember a song from an ad?

I seen a commercial a while ago, and I'm trying to remember the song that was played. It was a popular song, but I can't remember what it was. The commercial showed a black and blue cit with blue streams on light bouncing across different buildings, showing a connection between them. I'm pretty sure it was an ad for a new service, possibly a wireless phone service, I'm not 100% sure.
