GNOME Bugzilla – Bug 705307
Date tag not detected properly on FLAC files (and possibly others)
Last modified: 2013-08-01 22:09:13 UTC
Rhythmbox refuses to read DATE tags in vorbis comments of FLAC files, displaying 'Unknown' instead. For example, the year in the following tag... [..] comment[3]: ALBUM=Absolute comment[4]: DATE=1989 comment[5]: TRACKNUMBER=01 ...is displayed as 'Unknown'.
this was fixed in commit d78b2db
