So I was trying to upload files for two music mods I made, and I kept getting denied.

I get the message; "Hello, your file submission (etc).zip has been rejected." without any explanation for the reason it has been "rejected".

These songs are:

Metallica - Disposable Heroes

and

Valentino Khan - Pump

(One of these has a lot more influence than the other)

I'm leaning to this being a copyright thing, but assuming things can only get me so far.

If anyone knows of a support section somewhere where I can relocate this, please let me know, as I don't know if this is the right place to ask this.
