Give me a break!
I frequently hear a tune on the TV in an advert and can’t quite connect it to the name of the song and artist. Normally I’ll come across it a few days or weeks later on my iPod. There are various ways of overcoming this musical conumdrum including Shazam where you play the offending tune into your phone and they text you back the title and artist. If they don’t recognise the tune they’ll ask you for the details to add it to their database. By far and away the easiest one is the Commercial Breaks and Beats website which lists each of the adverts and the accompanying song. Everything you ever needed. They also kindly provide links to Amazon and iTunes should you want to but a solid or see thru version of the song.
