OK, so I've tried this various ways and nothing has happened. I'm sure I'm missing something simple, but I guess I need some help before I blow my stack with frustration over my own stupidity.
The title field for these albums was originally formatted as: (track number) - (artist name) - (song title). I wanted to remove everything before the actual song title. So I used the usual method for removing track numbers as a regular expression, which worked fine.
This left the formatting as (artist name) - (song title). So I figured I'd just finagle the number removal expression to remove the artist name, but that didn't work for some reason. And now I've tried a number of things I found in the forum to remove unwanted text from the field, but nothing has worked so far at all.
So, what simple expression am I missing here for removing this unwanted text from the beginning of my titles?
