Is there a way to convert capital letters to lowercase?

Downloaded a HUGE file. 100 songs. The artist and the title are in caps!!!!!

I've used the conversion before for various things...but I can't think of a string to reduce the caps to lowercase!

I normally wouldn't care, but since it's in caps, it messes up my zune's artists section and throws people (and sometimes me) off

Create yourself an action of the type "Case conversion" (or what that is called in English) (to create an action see FAQs /t/967/1
Enter the field where you want the case to be adapted.
Select a method - usually "normal" is normal ...
Repeat that for the other fields that have not the right case.
