Part of the long-term appeal is that the music isn't gimmicky. Instead, it's straight forward danceable, sing-able, and whistle-able music.

It's also not linked to any specific type of formal dance. Instead, dancers can do their own thing, which gives it a delightfully loose feel. It goes straight to the hips, feet, and heart.

On top of that, it involves ensemble playing, which still grabs people, be it performed live or be it played back on anything from earbuds to a superb audio system.

In my view, these attributes give the music a timeless appeal, and if the music business churned out and promoted lots of this music then lots of people would eventually end up buying it.
