Yes, you can do that. I tend to use that for rare and hard to get music (e.g. obscure iranian 60s stuff).

However cutting the full albums apart and tagging the resulting songs is serious work that I don't think a lot of people would do realistically in times of spotify.

I once used this tool for downloading music into SD cards for our car, this was when we were on road trips I sometimes capped out my data. But I used my spotify playlists to direct the youtube downloads, so I already had some paid access to the same music. Nowadays its just not a problem any more, and I simply use spotify directly.

i prefer

which downloads opus @153k (48000Hz) (use -F to check available formats)
