Okay so for renaming files I got it setup like this: $replace($num(%track%,2)-$lower(%artist%)-$lower(%title%), ,\_)  
This will give me a file name like: 01-artist\_name-file\_name's\_here.mp3  
What is the code to give me: 01-artist\_name-file\_names\_here.mp3

$replace($num(%track%,2)-$lower(%artist%)-$lower(%title%), ,\_,'',)  
the code to give: 01-artist\_name-file\_names\_here.mp3
