I like all 3 songs and have heard the first and last one just recently at home. My husband likes the oldies and we have CDs I put on at night sometimes for him to fall asleep to since he and the dogs usually go to bed at 7 or 8 pm and that's too early for me. It's been interesting hearing about the connections between the 3 songs. I don't think I've ever had more than one song in my head at a time. It's crazy though when you get a song going and can't shut it down for a day or two.
