Call me old-fashioned, but I have actual files on my external HDD. I use online services only for finding new music to listen to, and let me tell you, that's a lot of effort for very low yields, so I don't do that very much. I've been using mostly YouTube for that, although I dabbled in Spotify a bit in the last year until it threatened me with a potentially worse time, seemingly because I had run out of free something. I've also discovered YouTube Music to be quite nice, because whereas YouTube often delays playback start when using an adblocker in Firefox, YouTube Music has no such nonsense.
If YouTube Music has the same audio quality as YouTube itself - and I have no reason to doubt it - that's some really low-quality audio, I can tell you that much. Not by my ears though, because I'm not exactly an audiophile, but judging by what quality options a YouTube downloader app offers, it's pretty bad.
