Hello and always big thank you for this great program !

Right now I’ve the following string to rename the filename  
$num(%track%,2). $left(%album%,25)\_%title%

I’d like to change it in $num(%track%,2). XXXXXXXXX\_%title% where  
XXXXXXX is the second word of %artist%

Example: artist George Michael ——–\> 01. Michael\_Careless Whisper.mp3

Is it possible ?

Thank you for yr help  
MM

Take the contents of the field %artist%,  
Select any bunch of characters until you hit a space, then take then next bunch of characters and remember them.  
Finally output the remembered bit.
