Mesmerizing commercial

At Em's Pepaw's house (while watching some football), Aunt Valerie and Uncle Cooper noticed that Em would stop everything she was doing and stare at the tv when the GMC Sierra commercial came on! The next week at Vonnie's house, the commercial came on again - and same reaction! Weird! J thinks she likes the music. This is the commercial: http://www.youtube.com/watch?v=tOKdO3Wvsg0. Careful! It's mesmerizing!
