Forums Scripts & Popups $sfile and multiple file types

well yeah it does shuffle
but thing is when i have more than 1 file on list
it calls 2nd after first and thats ok

but when i have only 1 song it plays it and stops it
therefore no repeat

and all this happens in this fluffy alias :P
thats why i need someone (if willing) to explain
each procedure so i can put somewhere that crap with
/set %mp3repeat ON

:P
