I think it's a great idea too! I can't recall how many times I've been at a company party and have had a line of co-workers come up to me and ask about a song in a commercial b/c I'm the 'music guy.' Why should the advertisers hide this information? If I was in a band and a huge corporation wanted to use our music in an ad I'd say of course but only if the advertisers put our name and the song title plain as day in the commercial as well.
