Notes on adding "performer" tags - Ceejay 29 Dec 05
NB - Baseline code is 6.5b1 5425
Line number references might therefore vary slightly (or even a lot!) depending on which exact version you have!

===================

C:\Program Files\SlimServer\server\Slim\Formats\FLAC.pm

Around Line 43:

my @tagNames = qw(ALBUM ARTIST BAND COMPOSER CONDUCTOR DISCNUMBER TITLE TRACKNUMBER DATE PERFORMER);  # added entry

APE.pm, WMA.pm and OGG.pm have no equivalent to this tag list for codeset adjustment so should be ok as is.  

In MP3.pm I've not tested this but it looks like you could add (somewhere around line 59, say)

# get performer
	$MP3::Info::v2_to_v1_names{'TP1'} = 'PERFORMER';
	$MP3::Info::v2_to_v1_names{'TPE1'} = 'PERFORMER';

	'BAND'        => 4,
	'ALBUMARTIST' => 5,
	'PERFORMER'   => 6,       # added
);

Performer added (anywhere you like but near COMPOSER seems sensible)
