MNK Hunting Log

Can anyone answer a quick question I have real quick? I am making a video about the MNK hunting log and its a little over 10 minutes long and was thinking about adding some music to it, but I still don't know if you are allowed to do that or not. I know it says on SE's main movie making guide you can't, but I have seen some FFXIV AMV's (well alot) recently that have music, and someone on the forums even told me you are allowed to use music as long as you are not monetizing from it.
