Saw this yesterday on the EndeavourOS forum and thought more ppl might enjoy it.
I don’t use YT logged in so this is a really nice way to use YT for music imo with saved playlists and a smart list thingy that seems to find stuff I want to listen to from the same artist etc.
About privacy etc. from the dev:
I’m going to try this right away. I’ve been looking for a better way to watch YouTube without actually going to the site. Thanks
Bing allows you to do that.
Or you could use a competing music service which supports Linux like Spotify, Amazon Music, or the Open Source Pandora music client
I think even iHeart Radio even has a Linux client
This is an excellent player. Discovering new music isn’t easy and this makes it pretty easy. The UI is a little odd at first glance but it makes sense after a few minutes. Thanks for sharing!
This is more for finding new stuff and I have not had any good experience with Spotify and the like earlier. I got weird taste so I understand that the algorithms can’t help me properly 
On YT you get the recommendations based on what ppl have in their playlists and what others have watched etc. When playing an instrumental version of a song from Equilibrium (heavy metal) in Olivia I get ONLY instrumental after that which is what I’m after. I don’t care so much about the artists, I care about getting the singing out of the way 
I mostly buy the music I want to have but only if it’s files I can download and do whatever I want with.
That pesky singing, just wasted time between guitar solos.
