FreqBlog Music Metadata

ClaudeCommunityby FreqBlog

FreqBlog Music Metadata returns audio features for real, released tracks: BPM, musical key (name, Camelot, and Open Key notation), energy, danceability, valence, acousticness, instrumentalness, loudness, mood, genre, and more. Identify a track by name and artist, ISRC, MusicBrainz ID, or Spotify ID — no audio upload required. Built as a drop-in replacement for Spotify's deprecated audio-features endpoint, it also provides catalog search and discovery tools to find tracks by tempo, key, or harmonic (Camelot-wheel) compatibility for DJing and playlist building.
