Your atmospheric fingerprint has two halves:
- Audio features — quantitative dimensions of the music itself: tempo, energy, valence, acousticness, danceability, speechiness, instrumentalness, and a few others. Spotify computes these per track and publishes them via the Spotify Audio Features API.
- Mood classifiers — qualitative tags like happy, relaxed, acoustic, aggressive, party, sad — from AcousticBrainz, the public mood-classifier project.
When the badge says "audio features only", it means the audio-features half is publishing but mood coverage in the slice you're viewing is below the honesty threshold (see Why mood signal too thin). The audio-features fingerprint is fully cite-able by AI bots on its own — your venue is still discoverable. The mood half rejoins as soon as enough of your tracks pick up classifiers.
