preppy rock
Rock music that is played on the Top 40 stations/Radio Disney/adult Top 40 and is liked by preps.  Usually the singers sing about cleaned up, preppy  topics such as girlfriends, boyfriends, going to the beach, having a lot of money, the prom, going to parties, etc.  The guitars are  not as heavy and the music is happier and more melodic.
