As pointed out I am new to MB and just getting in to ways of working. The reason for highlighting then in the Set Display column area is then I just have the titles I am dealing with. If I put then together in the title field I could have many songs in between where the spelling was wrong or a punctuation put in the wrong place. Control and clicking them in the Set Display area means I have a clear view of the titles I am dealing with in the titles field, I can further control And click for the ones I want to edit or remove.
MB appealed to me as it ignore "the" prefix in title as well as in the artist name, invaluable for groups, plus it's speed. I am going to give the the sort formula a go and see what the results are
Do not mind putting work in to something if you can get it to do what I want. I use Calibre for my e-book collection and that again allows so much customization and I want to be able to do the same in MB
