Isn't the music the most important part of an ad? It can make you love one for no apparent reason and you will probably remember that song forever.
Here are some ads with great music that I gathered. Some are recent and others were on TV more than 10 years ago. Hope you like them and get to know a few great songs if you didn't know them already!
(I'm from Spain, so some of the ads were only broadcasted in my country, but they're cool and the songs are still superb anyway).
