Expression Question - Remove Artist from Title - Please Help!

Hi Everyone,
I have Artist - Title, as my filenames (which shows up as Abba - Dancing Queen) in MP3Tags Title field.

What I need is, the Title only and to lose the Artist and hyphen before it. I go to Actions/Quick Actions/Replace with regular expression but from there I'm well and truly stuck!

What do I need to enter guys?? Thank You so much..
Please Help!
Ray.

When you first imported the data as described in this of your threads:

how did the artist get into the title (again).

Try an action of the type "Guess value"
Source: %title%
Target format string: %artist% - %title%
or
Target format string: %dummy% - %title%

Hi Ohrenkino,
I know what you mean..it's strange: My filename is Artist - Title but for some reason I've cocked up. I'm trying to leave the filename as it is but then have artist (in the artist field) and title (in the title field) I have obviously done something wrong. not of of the database has the problem but enough to need to sort them. I could manually take out the artist and the hyphen but if I could do them all at once it would be a lot easier. Trying your tips now as I speak - I'll let you know..Thanks so much.

Still no good - lets try to be a bit clearer look at the image below:

You can see in the Title field it's the Artist & Title, all I want is the Title only.

Hope this helps
Ray.

what from my suggestions have you tried?
Because

should have that effect:

Hi mate - SORTED! your tips seem to have worked....Brilliant!
Thank You Ohrenkino....
Really Helpful!

If you have a filename like
Andrew Sisters - Chatanooga Choo Choo.mp3
why you don't use the most direct way to fill ARTIST and TITLE with

Convert -> Filename-Tag with
Format string: %ARTIST% - %TITLE%
