Defining bubblegum is a tricky proposition as the term variously describes: 1. the classic bubblegum era from 1967-1972; 2. disposable pop music; 3. pop music contrived and marketed to appeal to pre-teens; 4. pop music produced in an assembly-line process, driven by producers and using faceless singers; 5. pop music with that intangible, upbeat 'bubblegum' sound.
