from KB:
The contents of the the WORKID tag can be pretty much anything: you could just use a simple number sequence “1, 2, 3”, or you could use something more descriptive – e.g. Düsseldorf Oct 1963, London Jan 1964, Chicago Apr 1966 – as long as the same value is in the tag for all tracks of the same performance.
Can this be used to sort performances by date, intermixed with the TiVo dates? I need this really badly.
If WORKID is not the way, is there another way?
Thanks @joel!
