What do I write in the actions configuration (I have to make a new one) to convert the first letter, if small, to large? In more easily understanable form:

How do I convert:

brittney spears - sound of silence.mp3

into:

Brittney Spears - Sound of Silence.mp3

In other words: I want to convert all the beginning letters into large, except in words like "of", "in", "the" (if not in the beginning) etc etc...

Thanks!

Hello!

You can create a new action for case convertion. Make sure you select "Sentence" as type. MP3Tag will then capitalize the first letter of each word.  
After that, you can create several actions which replace "In" with "in", "At" with "at"... if they are not at the beginning (use RegEx for that).

Regards,  
Sebastian
