I was looking for KDE music players. Only Amarok and Elisa are KDE projects out of the ones you listed. KDE's six music players (yes I found another one) are Amarok, AudioTube, Elisa, JuK, Soundcloud Player for Plasma Bigscreen (great name) and Vvave. Source: over 1 year ago

The second app doesn't have local file music functionality, but is basically another Youtube Music Premium access app for KDE....again, for free. It is called AudioTube. Source: almost 2 years ago

I don't know if it would make things any better, but there's a free classical music "wrapper" for Spotify called Concertmaster: https://getconcertmaster.com/. Source: about 1 year ago

If you have Spotify premium give https://getconcertmaster.com/ a try. It's a frontend for Spotify with additional cataloging features for classical recordings. - Source: Hacker News / over 1 year ago

Concertmaster solved my issues with Spotify and classical, it's basically a Spotify wrapper for classical that makes it work a hell of a lot better. Source: about 2 years ago

Maybe this help https://getconcertmaster.com/ (I don't use it, just know it exists). Source: over 2 years ago

Hey everyone! I mainly use Spotify for full length albums and EPs and rarely listen to playlists. I was wondering if there is any alternative frontend for Spotify which has an easier way to visualize and sort my saved albums. Basically something like Concertmaster but for all music genres.
