My favorite is 2raumwohnung. I have also enjoyed Einsturzende Neubauten's newer albums, though I really would label them an "acquired taste."

all bad kiddy msuic here
try out

MIA. or Clusou

Wow, you guys know Christina Stürmer? That is really cool. And yeah she's Austrian. She attended a casting show on Austrian TV and became 2nd. :)

For more pop oriented music you can try out the "No Angels". They are a girl grop who sing in English and were heavily successful a few years ago.

Hmm, nobody has mentioned Nena so far. You all know her "99 Luftballons" song, but she has actually done many other great songs. Listen to "Liebe ist" which was a No. 1 hit in 2005 (so she is not a one-hit-wonder here :D).

*cough* *cough* Tokio Hotel *cough* :roflmao

if you want german pop, Cinema Bizarre is it. But they sing in English.
