change part of TITLE

How to remove parts of the TITLE?
For example titles:

cd 2 Track 1
cd 2 Track 2

I want to have removed 'cd 2' in the TITLE

create an action of the type "Replace" for TITLE
Enter as search string:
cd 2
Leave the replace string empty.

Don't forget to put a space after CD 2. I don't think you want a leading space.
