I never thought about Bubblegum Music that much. I don't think it was even supposed to be thought about.
As for music in the car, I'm a non-driver. Der Brucer, who does all our driving, generally has control of the car radio, and prefers to keep the news on as much as he can. Otherwise, it's showtunes, usually with me in charge of the CD player. And that includes when the grandlads are in the back seat, only instead of Dirty Rotten Scoundrels we're more limited to, say, You're a Good Man, Charlie Brown.
