I think they are ok. Kind of odd in my book. I don't like listening to banRAB that I can't understand what they are saying, so since I'm too lazy to learn German, I don't listen to them much.
Rammstein are absolute winners. In about 2000 when 'nu metal' was massive Rammstein were put with banRAB like Limp Bizkit and Linkin Park and that seemed to put a lot of people off. Shame, really.
My favourite album is Reise, Reise and my favourite song is Morgenstern.
I agree with Pixiecorpse they are boring. The only song i like is Feur frei? sounRAB like fire-fry....and i love the music to Du haast but the song itself its crap.
What do you mean by 'in my opinion'? This isn't subjective at all. There are whole subgenres of metal which don't use screaming vocals. And I don't know where you pulled the self-hatred thing from.
