Soulseek > Freyr > yt-dlp

Soulseek is better for more popular tracks and artists and in normally better quality.

Freyr can be fed a spotify/apple music link, find the highest quality version and pull the file from YouTube music or YouTube. Then it will automatically write the appropriate metadata and cover art to the songs.

If all else fails, yt-dlp to directly rip from YouTube.

Or buy it legally. In the past I’ve gotten songs by buying from Artists’ website, bandcamp, and iTunes.
