Hello, I wondered how to rename my musics in [Title ([Live])], when it comes from a concert (noted as the album in the tags of the song), cause I have a lot of songs that are the original versions, but have also been played thrice in three different lives (and they’re all gorgeous!!), but i can’t just have the same song with the same title on my phone, i can’t tell which is which… And i can’t find the right script for this…
I tried:
$if($rsearch(%album%,[live]),$set(title,%title% - [live])) for all the different live versions that i had, and variants of that, but it either doesn’t rename the files, or replaces it with _mp3, which is even worse. Somebody help me please 
PS: [live] is really just the live i wanted, i put the same name in the first and second brackets, and didn’t put the brackets. Just in case
Most of the live music I have in my collection has disambiguation text on the recordings. So I use this script in Picard.
$set(title,%title%$if(%_recordingcomment%, \(%_recordingcomment%\),))
This means each track now has a separate name with the concert details attached.
