Last week on All Songs Considered they talked about your parent's music collection during your youth. Essentially, they discussed the soundtrack of your childhood; the music that was played in the background before you "discovered" music of your own.
Because of my mom I know every word to every song played on "oldies" radio stations. The dial on the car radio was permanently fixed on the oldies. Mom also had some cassette tapes that she didn't mind listening to over and over again. She played Rod Stewart, Carole King, Carly Simon, and folky-classic rock mixes made by my dad and godfather.
