I beg to differ lol. Their music is amazing, and the show they put on is amazing. And ok, if people don't want Iron Maiden, how about Dragonforce? They're a younger band with incredible metal music:
Also, as stated, good music transcends language and ages. I'm a young furry. I'm 28 years old, and I love classic rock and especially metal. I don't care what the language is as long as it's good. Plus, foreign bands like Rammstein are additionally fun cuz it's fun to be able to learn some of the lyrics and, in doing so, learn another language. What Rammstein has that makes them connectable to everyone is how much goes into a Rammstein song and show. Firstly, it's heavy on the guitars and drums which fans of rock like. If you're looking for visuals, their pyrotechnics and stage visuals are insane! They have one called Engel (which translates to Angel) in which Till dons metal wings to look like an angel. The wings shoot out fire at the ends because it's Rammstein. The visuals help you understand the story even if you don't know the language. And the thing is, you don't even have to know the words of the band. Just seeing what they do on stage captivates an audience with how amazing they play their music.
