poblem with same title albums

[kingy1101]

hi there, im currently running MinimServer 0.8.5.3 update 129 on synology disk station .

i have a problem with a few flac albums that are titled: Greatest Hits which i have 4 or 5 of.

some of them are completely muddled with the wrong album art and the tracks get muddled. i am using glider audio on my phone.
when i use the plex server, all the albums show perfect, however plex doesnt have gapless flac playback. my tags for each album are as follows:

ALBUM
ALBUMARTIST
ARTIST
DISCNUMBER
TITLE
TRACK
YEAR

then directories

Music/Albums/ARTISTHERE/ALBUMNAME

any ideas?

cheers
