[ID3 Dev] NUDGE: Tags used by common MP3 players?

[Michael Makuch]

Below is the list of tags which I have come to support in my version of
the id3 util found in the id3lib. My www.muzikbrowzer.com uses TCON TPE1
TALB TIT2 TRCK TLEN TYER APIC.

I use TLEN as sort of a suggestion. I will display TLEN if present (in
appropriate places) but then if/when I have the opportunity to calculate
the actual  duration then I override the TLEN. TYER I use for displaying
albums in order of release date.

$ /usr/local/bin/id3
id3 [options] <file> # w/out options display tag info.  options:
     -v      <value> # id3 version (1 or 2)
     -dt             # delete tag (version 1 or 2 if specified else both
     -df     <value> # delete tag field
     -getart <value> # getart, writes to <file>
     -TCON   <value> # genre
     -TPE1   <value> # artist
     -TALB   <value> # album
     -TIT2   <value> # title
     -TRCK   <value> # track
     -TLEN   <value> # length
     -TYER   <value> # year
     -TPOS   <value> # part in set
     -TPUB   <value> # publisher
     -UFID   <value> # ufid
     -TMED   <value> # dig...
     -COMM   <value> # comment
     -APIC   <value> # art file, reads from <file>

Cheers
