I love that my work uses CD players to play music for all the classrooms. Our corporate overlords dole out the appropriate CDs that we're permitted to play on them. Who says you need an internet connected computer to play music for kids? CDs are ad free and you can replay the same song over and over again without any extra fees.

I'd sell you my CD player, but it's almost dead itself, BUT I will say they still exist and you can still buy them new.
