Year released is a record of the year that the disk was released. It is a simple 4-digit input in the playlist entry form that is optional and may be disabled.
Year released is interesting to both DJs and listeners for various reasons:
- If the music is unknown to a listener or DJ then release year helps contextualize the music
- If the album has several releases, release year helps identify which of these was played
Disabling this field has no significant negative consequences other than loss of this information and that it cannot be used as a search criterion or in report generation.
