I don't recall what the commercial was for but I think it was a music downloading service. The commercial features a few different scenarios with music that doesn't fit the scene (rap concert playing polka music, etc.) I am looking for the song with what sounded like a women sing a country song sped up to a hip hop beat. It played while people were country line dancing. All I could make out was the word "shaking" and then things that rhymed with it. The commercial ran last year. HELP!
