Music Data & APIs
Music data and API tools sit underneath everything else in this directory. They listen to audio and return structured data: genre, mood, BPM, key, and instrument tags, natural-language descriptions, similarity matches, and live performance data. Publishers and libraries use them for music catalog management and sync licensing metadata. Builders use them as the music understanding layer inside their own apps. This directory tracks what each service returns, how you access it, and what it costs.

Music Data & APIs: common questions
What is a music API?
A music API is a service your app calls to get music data back: tags, metadata, similarity matches, recommendations, or event listings. Instead of building audio analysis yourself, you send a track or a query and receive structured results. Cyanite returns genre, mood, BPM, and key tags from raw audio.
What is music catalog management software?
Software that keeps a music catalog searchable and licensable at scale. It combines storage, metadata, and search so a publisher or library can answer a sync brief without listening through thousands of tracks. AI tagging services plug into systems like DISCO, Source Audio, and Synchtank to fill in the metadata layer automatically.
Can you build a music app without coding skills?
Increasingly, yes. No-code platforms like make.com can call music APIs directly, and AI assistants handle the glue code. SyncMyMusic built its sync matching platform on the Cyanite API in 2.5 months this way, without a traditional developer on the team.
What data can AI extract from a music file?
Current audio models return genre, subgenre, mood, BPM, tempo, key, instruments, vocal characteristics, energy level, musical era, and suggested use cases, plus plain-language descriptions of how the track sounds. Accuracy varies by service and genre, so test against tracks you know before tagging a whole catalog.
Why does music metadata matter for sync licensing?
Music supervisors search by mood, scene, and feel, and a track they cannot find is a track they cannot license. Clean metadata is what makes a catalog searchable, which is why publishers treat tagging as revenue infrastructure rather than admin.
