I introduced my wife to Funkwhale, and she’s been ripping all of her old CDs from high school.
Not only did she not label all of the CDs, some of them were mixes from friends that had surprise mystery tracks added in as a joke.
In one case, she had a ska band cover of a song from Rocky Horror that even Shazam couldn’t identify.
Honestly, if they just made it easier to craft a formula (like, I dunno multiple lines, some kind of better color coding of matched parentheses, etc), that’d go a lot farther.
