Rammstein!
It's heavy music, but I love it.
Try the song
Sonne :O
I also recommend the uberclassic "
Zehn kleine Jägermeister"
When I was young I used to listen to the band Echt, they had some unique songs (
Du trägst keine Liebe in dir,
Junimond,
Wo bist du jetzt?) but that's the music of the 90's, not sure how it's perceived by today's people.
It brings back memories
I learned german by watching anime with german dubbing when it was still unknown in my country
I have some more good songs but they are all from the 90's :p
