Just google "Absolut kidz" or Just Dance kids for tips. Or why not ask the kids what they want to hear, evaluate it, then vote on it. Have themes (like 60s, 70s, 80s, musicals, etc.) and learn about the era%theme.

If it's 7th grade, I'm guessing that you stay put and have a different group of kids come in and out every hour or so?

I'd feature 1 artist per day. Otherwise, different kids will hear different parts of the playlist.

Or is this just for you to keep your sanity? LOL.

10cc - The Dean And I

This brings up horrible memories

What does? 10cc, falling in love with the dean's daughter, being in 7th grade, or teaching 7th grade, or planning music time for grade school kids?

Teaching 7th grade

No matter what music you play they’ll bitch and moan and say it sucks.

****ing hate kids that age

Hey I know what you mean. The Album Club 2017 was like teaching 7th grade for me - a very traumatic experience.
