Quick Action for Title Names

I've got a lot of MP3 files to tag and I've been trying to figure out how to fill in the Title fields using quick actions.

For example:

My MP3 Files are named as such: Artist-Song Title (No spaces before or after the dash but I can change that if I need to using "Replace".)

How do I fill in the Title field so that only the Song Title will appear?

I know this has got to be basic but I've looked all over the forums, tried Format Value, Replace, Replace with Regular Expression... Either MP3Tag doesn't respond or it tells me 0 of X files changed. What am I doing wrong and how do I make it right?

Use either teh converter filename - tag with the mask
Or use an action of the type "Guess value" for %_Filename% and the guessing pattern

Worked Great! Thanks! You just saved me a ton of typing.
