They promoted a playlist. The playlist grew 1,200%.

The setup

Biking with Francis, a dynamic trio, had a new single called CERBERUS and a curated playlist built to match its vibe. Instead of promoting the song alone, they asked a better question: what if the playlist and the single could grow each other?

The play

They ran Symphony's Grow Playlist Followers playbook with CERBERUS as the anchor: the song linked inside the playlist, and the campaigns drove traffic to the playlist rather than a bare streaming link. They targeted audiences around their own identity, including biking, and let the creative carry the vibe.

They started small, watched the cost per click and cost per conversion come in strong, and scaled the campaign up over two months.

The hidden win was algorithmic. With CERBERUS sitting among similar songs by similar artists, Spotify began associating the track with its neighbors, extending the campaign's reach beyond the paid traffic.

The results

The playlist grew 1,200% and followers grew 40%, with streams of CERBERUS rising substantially as listeners discovered it inside the list. The campaign metrics stayed cheap throughout, and the band came away owning a growth asset that outlives any single release.
