How would I put a space after "(" in certain song titles? Example: Don't Be Cruel(Live)
(Let Me Be Your) Teddy Bear-Don't Be Cruel(Live At Convention Center Arena, San Antonio, Tx-April 18, 1972)
Do you really want it to look like this:
Don't Be Cruel( Live)
(space added behind bracket)
or should it be
Don't Be Cruel (Live)
(space added in front of bracket)
Also for this case, I repeat my note as mentioned here:
You will find several TITLEs where this will lead to unwanted changes.
Example:
Q(Uarantine)
becomes
Q (Uarantine)
or
Abstrac(tion)
becomes
Abstrac (tion)
Just a few more of my current TITLEs:
Memory Lane (Luv(Sic) Part 2)
Take the D(on’t Give a Fuck) Train
Incassable(S) MMXXII
Con(Clusion)
Meine Ex(plodierte Freundin)
This is how I would like it to look "Don't Be Cruel (Live)"
Create an action of the type "Replace" for TITLE
Search string: (
Replace with: ⎵(
Which becomes 
⎵(Let Me Be Your) Teddy Bear-Don't Be Cruel (Live At Convention Center Arena, San Antonio, Tx-April 18, 1972)
I would remove leading and trailing blanks as described in the FAQs:
