Lou Plummer replaced Apple Music with some apps and an iPod:

Using a big old iPod Classic forces a certain discipline.

1. Everything must be local. No cloud placeholders. Availability becomes certain instead of the streamer’s gamble of “is this still licensed?”
2. Metadata has to be correct. Artist, Album, Genre, Composer, and Year matter because that’s how the device navigates.
3. Portability means independence. The device doesn’t call home to verify a subscription.

It’s a surprisingly healthy constraint.

I’m probably not going to do it, but there is something appealing about the iPod days of yore.
