When updating from 0.13 -> 0.14 of mpd the internal database format seems to have changed (db_file "/var/lib/mpd/database"). Previous versions of mpd stored the metadata in some format, however when updating to 0.14.2 this older format is only being used in some form of backwards compatibility. This has as a side effect, that metadata is no longer stored in the database and thus is no longer displayed. Submitting an update command to mpd will update the database, but only using this older format. The user has to stop mpd (and probably remove db_file) and run mpd --create-db to create a database based on the new format. Reproducible: Always Steps to Reproduce:
Created attachment 187892 [details, diff] add warnings to ebuild when upgrading mpd. Add some information to inform the user to update his database format if he wants metadata like artist, title etc to work properly again.
