depends if you want a german rock band with english lyrics or should it be more like Rammstein?
in case you want english lyrics you should listen to "Running Wild".
i love them! really, you should try it! you can also try Scorpions but i am sure you already know them.
otherwise you could listen to "Troopers", their lyrics are about good old times, drinking and sometimes brawling:D
http://www.youtube.com/watch?v=BWD4rMTriJ8 ; Troopers - Scheißegal. it means "fuck off".
the text is about about today (whats going wrong) and that they would live their life again, "Scheißegal" whatever happend!
my favourite song of Troopers (yeah the voice sounds like one of that foolish racist singers but they are against racism ^^)

normaly i just listen progressive house and things like that. but my dad was a old school rocker with long hairs 25 years ago driving around with his steel helmet on his harley davidson. thats why i love scorpions, iron maiden, black sabbath, Running Wild, Motörhead and many more bands
