format album name

i have got album name as this
come with me-norah jones[abc.com]

i want it to be like this
come with me-norah jones

how to get it? kindly give instructions. guess value-- i tried %album%-%album% %dummy% with drastic result.

another example of album name
beatles-hits of[abc.com]

i want it to be as
beatles - hits of

another example of artist name
kenny rogers[abcdef.com]

i want it to be
kenny rogers

when i tried guess values-%artist%[%dummy%] i get kenny as artist name. (only the first word of the name)

kindly give suggestions. thanks in advance.

This pattern works for all examples:

Action type: Guess values
Source format: %album%
Guessing pattern: %album%[%dummy%]

but i tried that funtion and got only the first word as album name/artist name-- where it has two.

thanks a lot for the suggestions. it works!
