The numbers on the vinyl album renaissance are probably a good illustration. They're undergoing nonlinear growth, and have either surpassed CD sales or are neck-and-neck, e.g.: https://www.statista.com/chart/26583/music-album-sales-in-th... Though it's also interesting that actual CD sales have levelled off too, after dropping for years.

Other analog media like minidisc has also seen a notable uptick in popularity, albeit not nearly as much as vinyl.

Also while not analog, iPods modded to be a bit more modern (replacing their mechanical HDs with higher capacity flash and adding haptics and Bluetooth among other things) have also been popular lately.

Offline music is definitely seeing a resurgence.
