I use flac + embedded cuesheet for full cd albums, mainly for classical music. I found strange behaviour for the several cuesheet items summarised below. Is it a bug, or a feature? I believe, the first.
There is a header part of cuesheet before the FILE line, and a track part, where I can provide individualinformation for the current track only.

PERFORMER
If it's in the header, I must not use by track, if I use by track, the album can be find under various artist, in the detailed list the artist can be read. So I cannot browse by a track artist.

TITLE 
It's ok.

GENRE 
COMMENT
They are OK. If I define it in header, it is set for every track, but I can redefine this value by the individual GENRE/COMMENT defined for the current track.

YEAR
I can define it in the header and in the track area. If I redefine the header value in the track, I can browse it, but the song list will be empty. This is a failure.

COMPOSER
CONDUCTOR
ORCHESTRA
A cannot define it in the header, I must copy the same value under every individual track even it is the same value for all tracks.

Please comment it.
