Thank you both for your quick replies
The cue sheet concept will not work for me. I don't solely employ the MusicBee player, I also transfer approx 1,200 tracks to USB flash drives that I have plugged into half a dozen 'dumb' DAB radios [with colour displays that can show artwork thumbnails] at various locations - these devices can't read cue sheets, gain tags etc. - thus I need to use 'real' edits, but preserve album art etc. The radio/music players are in remote cottages that I rent out so networking isn't feasible nor desirable.
Q1 - so there is no plugin available that can enable simple MP3 edits of a track in my library?
Q2 - there is no link to a forum post that describes a workflow to simplify my tasks?
