SONOTELLER

SONOTELLER.AI is an experimental AI music analysis engine that can 'listen' to music files and analyze a song's musical attributes and lyrics content simultaneously, providing structured metadata reports for music industry professionals and music lovers. Founded by former Google product manager Edu Duque and now acquired and integrated by music licensing platform Chordal, it completes a full analysis in about 1 minute on average.

Core Capabilities

• Music analysis: Automatically identifies genre, subgenre, instruments, BPM, key, and vocal type
• Lyrics analysis: Extracts song themes, emotional summary, mood tags, language detection, and explicit content flags
• Golden Minute: The AI automatically locates a song's most exciting segment (usually the chorus), ideal for playlist curation and film/TV music licensing
• Automatic tagging system: Supports automatic tagging of large music catalogs, improving discoverability on streaming platforms
• DDEX standard compatibility: API output conforms to the DDEX metadata specification, making it easy for labels to distribute content to Spotify and Apple Music

Use Cases Music supervisors quickly screening suitable music for film and ads, record label A&R teams evaluating new signings, playlist editors curating lists by mood and theme, and independent musicians analyzing the elements of their own work. Any scenario that needs a fast read on 'what the song says' and 'how it sounds'.

Unique Advantages A rarely seen 'music + lyrics' dual analysis capability on the market, distinct from Cyanite's audio-only focus or Songtell's lyrics-only analysis. Lyrics analysis depth is the main advantage, and the 'Golden Minute' feature precisely locates emotional peaks. A flexible API is available through RapidAPI, and labels enjoy a 50% discount.

Editor's Verdict One of the most technically ambitious music AI tools around, and its acquisition by Chordal proves its commercial value. User feedback highlights high accuracy and fast processing, but it remains in beta with occasional random delays or inaccurate genre tags (such as tagging punk as 'alternative pop'). The free tier's 10 requests per month is limiting for heavy users, but for music industry professionals and independent musicians it is a highly cost-effective metadata tool.
