A marketing term used by producers to help artists find instrumentals that match the style of a specific famous artist (in this case, likely a "Hotline" or "Drake" type vibe).
This indicates the beat can be used for non-commercial purposes, though a "lease" is usually required to put it on streaming platforms like Spotify or Apple Music.
Studies on how producers use SEO (search engine optimization) keywords like "smooth" or "dark" to reach specific audiences [2].
