Music for the older, more opinionated, child

Anyone know of popular type music with clean lyrics? Particularly punk music, if possible. My son enjoys classical music, but asks for “rock music”. He enjoyed punk music as a baby, but I’m not very familiar with that genre and don’t know any songs or bands with clean enough lyrics.

I want to expose him to a wider variety of music in general, and he wants to hear “cool” music.

my daughter’s favourite… HELP, from The Beatles…

I love all the Kidz Bop CDs. They are well sung, many have kids singing the songs and all the questionable lyrics are changed or eliminated. They have CDs ranging from golden oldies, Christmas and so many more things. Mostly modern pop.
