How to remove/trim leading track numbers?
Action type: Replace with regular expressions
Regular expression: ^\s*\d+\s*-\s*
Replace matches with:
This regular expression removes the track number from 01 - Anything.. so that only Anything... remains.
^ matches the beginning of the string. Then any numbers of whitespaces \s* followed by numbers from 0-9.
The \s*-\s* part removes the hyphen and any whitespace characters around it.
