You know, the same thing happened to me but I decided to create a new account. It was a different situation, though, because I had a TON of legitimate videos and then one or two from TV shows and they decided that was copyright infringement enough to do away with the whole account. My bad, really, at least for being so STUPID. So I uploaded all the legitimate ones again and left it at that. But as for YOU - you are in touch with the bands themselves, aren't you, you run websites and all. You COULD try to get them to give you permission and then talk to YouTube about it. They don't delete anything, you know, they just don't allow access to it anymore. You could make this into "OFFICIAL" metal videos account, really. I think some bands (hey, at least sack trick!) would definetely be nice enough to say OK and to realise that's really good for them, you know, exposure and all.

Nahh, honestly I don't want to have all the hard work to talk to the bands and their managments, you know what I mean? Anyway, Sack Trick would be easy, Tribuzy would also be.... but then I'm not in the mood anymore.

I will in the near future creante another account and put video from my new band. Even though we're just playing covers at the moment, I'm not sure youtube will be smart enough to find out that the songs are indeed someone else's song! :p
