Comcast bashes AT&T

[Billiam411]

the commercial has been playing for a few weeks now but i'm curious if anyone knows what the music that is playing in the background of it is. the plot of the commercial is basically "once users realized att prices were going up and comcasts' were going down, they switched to comcast" or something like that. The piano has the melody, and a drumset comes in like half way through the commercial. I cant find a video of it, but if anyone knows what im talking about that would help.
any idea if its from an artist, or if it was custom written?

Thanks
