As someone who spends a fair amount of time on music forums where people pop in every day or so asking "Who did that song on that one car commercial?," I think this is a fine idea (if only so the rest of us who don't care and/or know how to use Google will be left in peace). It really seems like you haven't been paying attention to TV commercials lately - which is fine, I pay attention to them as little as possible myself, just maybe know what you're talking about before you post.
