Hi Coert,

When you add a new value in composer/producer field of some album, it should be added automatically to the drop-down list of composers or producers for all albums. However, there are issues with displaying drop-down list in fields of Track properties, but this is a known problem and it will be fixed on some stage.

Unfortunately, lyrics are not reusable. The only way to assign same lyrics to different songs is via data duplication.

Regards
Andrei
