Remove Artist and - From Title

All My Music Files Show Up In The Title Section As:

Eg. As Tall As Lions - A Break A Pause

I Would Like It To Say Only The Title Of The Song:

Eg. A Break A Pause

Is There Any Easy Way To Do This?
My Filenames Are The Same As My Title
Should I Change My Filenames To Just The Title Of The Song First And Then Convert That To The Title?

Thanks!
