Classical Extras 2.0

Well I’m new and posted this problem, but I think may be it’s here the correct place to solve the problem.

I wanted to have the composer last name at the beggining of “tiltle” (1) and if there is an orchestra, add the “band” at the end of the title keeping the composer last name at the beggining (2). Also it could be nice if that could be alternate with conductors 3, etc.

  1. Mozart, title

if there is and Orchestra

  1. Mozart, title, Orchestra

  2. Mozart, title, Orchestra, conductor

I have used the Tagg Mapping in this way:

The problem is when I have a “composer_lastnames” but no “band” or “ensemble_names”.

If I unchek the condicional, it repetes the “title” in the tracks with band like this:

But I would like to have only one string with “title”, and no to individual select the second one each time.

Thanks in advance for the help.
