Linking Music and Vocal into a Song

A Song links to a Music style and a Vocal style; when you copy or export the Song, those linked styles are merged with the Song's own content into one prompt.

This is what makes styles reusable - change a Music style once and every Song that links it benefits, with no copy-paste. Link styles when you build a Song, and reuse the same Music or Vocal across as many Songs as you like.
