Skimmed comments, but if you download and manage your music on your own on a machine you can have a super simple setup like I do. All music is synced using Syncthing to my phone. So my phone gets local storage, and then I use Poweramp (android) to play it.

I pretty much have a folder for all the music though. But I assume you can sort music into folders to have them as playlists. But perhaps not as practical as desired.

If you use it frequently, I suggest getting a GUI that have profiles or remember options so you don’t have to mess with commands all the time. I wrote my own little command line wrspper which is Windows only since I don’t have Linux to test on. Though it shouldn’t take much effort to add support.

Makes it much more convenient when you don’t have to specify things like archive (ignore duplicates), filename to be “artist - title” (where possible), download destination, etc. Just alt-tab, Ctrl-v, Enter. And the download is running. And mine also has parallel downloads and queue for when you got many slow downloads.

It’s a link to an image on github not sure why it doesn’t work for you. Try just looking at the repo then:

(Windows only warning, unless someone wants to add Linux support)

I didn’t really search around for GUIs way back, but ended up making a basic GUI because I wanted to learn programming.

With just having options as checkboxes for YouTube-dl. It has served me well all these years. It was literally the thing I made while learning programming so the code is pretty janky when I look back at it though…
