Youtube Music have no lossless, its "tracks" have no metadata and are stored in pesky format with a lot of stupid limitations about receiving them. Seems you just do not know what is a good music and how it even looks on your filesystem. And good luck about acknowledging (not even receiving) every existing recording of your favorite artist; discography.
It's perfectly fine for streaming and getting music recommendations, which is the topic of this thread. For the local music library I then purchase lossless versions of the tracks I like.
