How Choon tags your music
Metadata in, detailed tags out. Every track in your library gets classified in seconds.
It reads the record, not the waveform alone.
Choon reads the metadata already embedded in your tracks — artist, title, album, and label — then cross-references it against comprehensive music databases to understand each record's lineage.
The Mac companion app also listens to your tracks directly — analyzing audio characteristics like tempo, energy, and tonal qualities to give the AI additional context. No uploading audio files. Your music never leaves your Mac.
Four ways to slice your library.
Four tag dimensions that let you find any track the way you actually think about it.
Genre
Granular sub-genre classification, not just broad buckets. Your tracks get labeled the way you actually think about music.
Region
Where the sound comes from matters. Regional context helps you build sets with geographic coherence or intentional contrast.
Era
Decade-level timeline tags. Pull up 90s classics or narrow to fresh 2020s releases mid-set.
Vibe
The differentiator. Contextual labels about how a track functions in a set — not just what it sounds like, but when to play it.
No one-size-fits-all taxonomy.
Every DJ organizes differently. Choon tags your library in your own vocabulary.
Custom genre lists
Pick from 50+ sub-genres or add your own. Only the tags you care about end up on your tracks.
Custom region lists
Select the regional scenes relevant to your sound. Chicago, Osaka, Bucharest — whatever fits your crate.
Custom vibe lists
Define the moods and energy levels that match your style. The AI tags using only your vocabulary.
Your library, your language
The AI adapts to your selections. Two DJs with the same tracks can get completely different tags based on their preferences.
