The Start/End time crop the duration when it is use. For example; a
4:00
Start Time: 2:00
End Time: 3:00
Will make this track to have a duration of 1:00 whenever it is play. The problem with this method is all my synchronize lyric will be out of sync. MusicBee should handle it differently, one way is to just skip to start time, and change track at end time rather than the current system.
