I'm afraid I don't know the answer, but if the advert is still on you could use 'Shazam' to find out the artist and title. Dial 2580 from your mobile and hold the microphone toward the speaker. Shazam takes a sample of the track and a very nifty program shold recognise it from their samples and automatically text yu the name of the track back. It sometimes takes up to half an hour or so, but it really is a clever system. It's generally not affected by background noise or even speech over the track. Good luck!
