Presave to Spotify campaigns allows users to connect on Spotify in order to follow an artist and "pre-save" their upcoming album or single on Spotify. What this means is that once the single is available for streaming, it will automatically get added to both their Spotify library plus a Spotify playlist. While most pre-save campaigns focus on albums, this rather successful campaign was used to help launch a new single from 300 Entertainment's Cheat Codes.
