Something similar was requested a while back where someone wanted to export details of the currently playing track to a file. [url=https://www.mediamonkey.com/forum/viewtopic.php?f=27&t=98435]The thread[/url] also contains the link to a sample extension that does that. It's a different use case of course, but the basic idea of collecting track information and writing it to a file is the same, you could take that extension as starting point and customize it the way you need.

OK, thanks.

MM4 is still running alongside MM5, so I can still use that for some tasks.

This was provided by an Addon, not MediaMonkey itself. No such Addon exists yet for MediaMonkey 5.

I often created CSV reports in MM4 using:

File -> Create reports -> custom reports

In MM5 I can see how to create a CSV using File -> Create reports -> CSV, but this selects set fields (eg: Artist, Title), and I need to select my own fields (eg: Last Played, Composer).

I'd be very grateful for help on this, I really need this functionality.
