Long playlists with music suitable for school breaks (inst jazz, blues, twist...) ?

[Mezurashii5]

I'm in charge of playing music during lesson breaks in my school, and I've been playing them some jazz piano "conversation" music, but I need things more lively because people have low tolerance for calm or negative sounding music (a minor scale, god save us!).

I'm thinking about jazz band, jazzy blues, twist, kind of ballroom-like music, but without vocals, decent quality and not too demanding for the speakers (they're godddamn awful).

Any recommendations appreciated :)!
