I'll explain what the regular expession here does, just incase you wanted to know.
$regex(file,%songname,/"(.+\.\w+)/)
Sets the name of 'file' to the regular expession so it can easily be called in a $regml later
Looks in the sting contained in the varible %songname
/"(.+\.\w+)/ This is the regular expression
the / at the start and end are used to set properties, but in this no properties are selected making the / and / useless
Then we have a ", this will look in the string for a "
The ( and ) marks what we want to be stored in the $regml.
After finding the the ", we want it to find anything, thats what the . does, we know SOMETHING is going to be after the " but we dont know what, and theres going to be more than 1 charector so we use a + to repeat the .
The \. states to look for the . charector (this will find the dot just before the mp3)
Then we look for any word charector with \w as many times as there are word charectors (a space isn't a word charector)
Hope this helps
