Overview
The tango.info music database contains a playing duration for some tracks.
The value is stored in the format "<minutes>:<seconds>".
The precision level of the value in the database is 1 second, but since different sources and techniques to obtain the value are used, deviations up to 3 seconds are considered to be within the precision of the database.
Sources
The data is obtained from different sources, among them are:
- tango.info product graphics
- display of track duration in a music player
- freedb (calculated from XMCD)
Pregap
The value can contain the pregap, e.g. for track 02 from

the duration could be
- 05:39:06 - 02:44:40 ~ 05:39 - 02:44 = 2:55 or
- 05:39:06 - 02:47:20 ~ 05:39 - 02:47 = 2:52
Gap position
It has been reported to tango.info:
Prefix on CD. Suffix when ripped to individual track files - except last file.
XMCD
According to http://ftp.freedb.org/pub/freedb/latest/DBFORMAT
The comments should also contain the string "# Track frame offsets:" followed by the list of track offsets (the # of frames from the beginning of the CD) obtained from the table of contents on the CD itself
valid XMCD files contain frame offsets from the beginning of a CD.
The standard does not define whether that is INDEX 00 or INDEX 01 as given in the cue sheets.
