The term Bubblegum pop is sometimes used to describe any pop music that may seem metaphorically "sickly sweet", but Bubblegum is actually an official genre itself.
Bubblegum was a type of rock 'n' roll in the late '60s and early '70s that was specifically marketed to teenagers, and often literally mentioned sugar and candy in the lyrics.
