I also would like to do the following:
Select All tracks, Right click, Edit, Settings Tab, End time 3:00, Save.
Play the tracks and each track would end after playing for 3 minutes.
This option is available in MediaMonkey and in Itunes but those settings will not transfer with the track directly into MusicBee.
This can be combined with the 5-10 second "crossfade" to fade at the end of the 3:00 minutes and 5-10 seconds of silence added to each track to provide a slight lull prior to the next track for a very professional effect.
I searched the plugin section for "Intro Mode" as you suggested in the previous post but only 'UPnP/ DLNA device support" plugin came up. The other plugins did not appear to accomplish this either. I also read any forum topic anywhere close to this subject but found nothing that would help. PLEASE tell me this plugin still exists.
The option to set the start/end time by batch would be very helpful when having a party or similar or you just want to listen to more tracks rather than hear the more lengthy tracks. It would also be beneficial for bars, dance studios, and other professional music venues.
It also still very important to be able to set the start/end time of individual tracks to sometimes eliminate the crowd noise, very long intros, etc. which is specific to that track.
Obviously other ways to accomplish this exist, such as mp3DirectCut, but the option to revert back to the original track length is preferred. And yes one could use MediaMonkey or Itunes but those are not the preferred music player. I am extremely impressed with what MusicBee has accomplished.
