Search result -> filename instead of name (For smart folders)

Can anybody help me out. I want to create a smartfolder with all my mp3's. I renamed all my mp3's to correct full name. For example:

Phil Collins - In The Air Tonight.mp3

When I create a smart folder. It shows all my mp3's but with the name from metadata (ID3 tag) so only In the air tonight. There is no way to select filename in the colums. This is really annoying.

Does anybody know a solution? Or another program that does the trick? Or a hack?
