This kinda feels like walking into a Burger King and asking how to order at McDonalds...but anyway...
There's very little you can do to circumvent the copyright stuff on Youtube. Not tagging the song or artist may help a little, but if Google's content matching could be defeated that easily, they wouldn't be using it.
That other thread you linked to doesn't have anything to do with youtube. It's only describing how you upload to our LOCAL
server. Sure, the general process of transferring files via FTP can be used elsewhere, but the thread as a whole is specifically geared towards this site.
If you're tired of youtube, you can always enter your video information into our catalog and then upload here. As long as it's mostly anime by our definition
(which is kinda outdated, but gives the general idea), and is set to some other audio, it's welcome here.
