Regular expression to extract the year from a string

Question

This should be simple but i cant seem to get it going. The purpose of it is to extract v3 tags from mp3 file names in Mp3tag.

I have these strings I want to extract

Answer 1

I'd go with

^(.*)\s\(([0-9]{4})\)$

(assuming all years have 4 digits, use [0-9]+ if you have an unknown number of digits, but at least one, or [0-9]* if there could be no digits)
