I’ve just mapped out a 7‑tier taxonomy for my music library—tempo, key, mood, instrumentation, era, region, and language. Think we could run a quick test to see how fast we can pull up a track from that structure?

Here’s a tiny mock dataset I use in the lab: Artist,Title,Tempo,BPM,Key,Mood,Instrumentation,Era,Region,Language The Velvet Echoes,Midnight Glide,Moderate,120,Am,Reflective,Strings,1970s,UK,English Neon Pulse,Electric Pulse,Upbeat,140,F#,Energetic,Synths,2010s,USA,English Silk Roads,Desert Dawn,Slow,60,C,Serene,World,2015,Middle East,Arabic Jazz Quartet,Blue Note,Moderate,90,Bb,Melancholic,Brass,1950s,USA,English Rising Tide,Oceanic,Upbeat,130,G,Adventurous,Electronic,2020,Japan,Japanese Café Mornings,Afternoon Light,Easy,80,Em,Calm,Acoustic,1980s,France,French The Quiet Hour,Still Night,Very Slow,40,D,Introspective,Cello,2000s,Sweden,Swedish Query: SELECT Title, Artist FROM MusicLibrary WHERE Tempo = 'Upbeat' AND Era = '2010s' AND Language = 'English' ORDER BY BPM DESC; Run that and let me know the time taken.
