I’m trying to implement mp3 uploads but the validation engine keeps  
flagging me every time i try to upload an mp3, “Content type is not  
listed.” I’m currently using ‘application/mp3’ as the content type. I’d  
appreciate any help.

-Thanks

Is there a good way anyone can think of doing this:

I want to read in the /etc/passwd & /etc/shadow and /etc/group file and  
prune all the accounts that are not necessary then use them as the login  
and password for my website. It will be an internal application that  
controls an automated install server.

audio/mp3 will work better for you.

Actually - the correct mime type is ‘audio/mpeg’, not ‘audio/mp3’
