It's an interesting toy, but I wonder if this isn't someone trying to hold back the tides of modernity by making their kids appreciate music the way they did.

AFAICT most of the old musical tribes we used to arrange ourselves into are a bit of a thing of the past (punks/goths/greebos/grunge/indie kids/ravers/etc), and kids don't build their identities around music taste any more, because music is no longer so much of a scarce commodity.

Sometimes things just change...

That said, as a fun tech project, definitely cool.
