Remove artist from %title%

Ah I see it changing the title as I was hoping for thanks @poster. However it's also pruning the first brackets from song titles.

Your example was:

Current song titles:
Song Title: 01 Dear Angie - Beatles
Artist: Beatles

Desired Song Titles:
Song Title: Dear Angie

If you have other files without a tracknumber in front you can't use the same format string.
You have to use instead
