A Medley is a piece of music that is made up of parts of other songs that when combined form a Medley.
If you submit a track that is a Medley, per music store guidelines, the title of that track must only contain the titles of each song that makes up that Medley and cannot simply be titled "Medley" or have a different title than the underlying songs that make up the medley.
The titles should be separated by the "/" character to denote each title.
No additional information should be in the title other than the titles of the underlying songs.
Example of a Track Title containing 3 different songs forming a Medley:
"How the West Was Won / A Lover's Quarrel / Take Me Back to My Home Town"
Further, you should also assign the individual songwriters or composers to the track for each underlying song in the medley.
