@ffolke: If the word "live" could be "anywhere" in your comment, it would be nearly impossible. Of course, one could build a regex to find "live" - but are you sure, that this "live" has no other meaning?
Whats about "live out there in the fog" or "live 8" or "live animal" - this could be tricky!
You are correct that "live" could be anywhere within the comment, but it can't be nearly impossible? As of right now, I know for a fact there would be no instances of "live" that are in the wrong context like your example. I would, however, like to employ this technique for styles or subgenres (that I put in comments) using the AMG script. I want to mass adjust several files for keywords that I think might be missing from AMG [ws]. What I don't want to do is create extra duplicate data that contains my desired keyword.
Unfortunately, I am very poor at RE's. And I couldn't get Sebastian's FormatValue to work. I tested with several files with different orders and configurations:
This is Live
Live in Concert
good and evil
Yet for some reason, Live was added to ALL files?!
Can someone give me some guidance? (or maybe a tutorial)
Please notice however that Mp3tag seems to differentiate between lowercase and uppercase and unfortunately, I don't know how to turn that off. Also, notice that my formatstring will find "live" even if it's part of a word like "alive" or "blahliveblah".
Edit: Sorry for writing this in German first - I am pretty tired at the moment.
