One possible exception, do you consider youtube an "intended method"? (A legit question for those of us who remember what a legal gray area they were in, in the 2000s.) Because the convenience of youtube replaced downloading music torrents, for me at least (who don't really care much audio quality). I only wish they would let me hear the music when I turn my phone's screen off.

Same here. Most of what I want to listen to is on youtube. I use the brave browser on my phone which both blocks adds and allows me to listen with the phone locked.
