Can you recommend some good german music???

If you like dance/hip-hop, try Jan Delay [Mercedes Dance (2007) or Wir Kinder von Bahnhof Soul (2009)].

If you like Urban, Culcha Candela is the way to go [Culcha Candela (2007) or Schöne Neue Welt (2009)].

Marquess is a German group that sings primarily in Spanish: I love their Frenetica CD (2007).

That's for starters....let me know if you want other suggestions.

Hello,
I suggest you my favorite German song (cuz I don't listen to much of it) :
Schwarz zu Blau by Peter Fox

And the translations here :

Enjoy

Matching your style, I like Sabrina Setlur and the silly Yvonne Catterfeld, who is lightly influenced by R'n'B

ROFL, I remember Sabrina Setlur with these Rödelheim boys...("Schwester S"),
Catterfeld I know only as an actress up to now, might be interesting to hear her sing

Well, what to recommend you: Fettes Brot, Fanta4, H-Blockx (have to check the spelling),
Hans Söllner (the anarchic Bavarian Rastaman)

Try Marteria (or Marsimoto). He is a rapper from Rostock/Berlin and really good, especially if you understand the lyrics

Jennifer Rostock are also good, seen them last year at the Spring On Festival

Duet Alkor – dance a single "Super tra-lja-lja" («Супер тря-ля-ля»):

Oh Well, I quite like Tim Bendzko but that's pop music. You could try Jennifer Rostock or maybe Laserkraft 3D. Then Casper, he's very good =)

Try Blumio! I really adore him because of his witty and funny lyrics.

Other great artists are: Clueso, Ryo, Max Herre and of course Casper and Marteria.

These are mainly pop, but they're pretty good. I can post more if you would like.
Cassandra Steen
-Darum Leben Wir
-Gebt Alles
Frida Gold
-Wovon Sollen wir Träumen?
Tim Bendzko
-Nur noch Kurz die Welt Retten
Bushido
-Vergiss Mich
Doreen
-Glück
-Ich bin meine eigene Frau
-Nicht wie ihr

And i like Christina Stürmer, LaFee und Ich&Ich

-Soehne Mannheims

-Rosenstolz

-Wir Sind Helden

-Xavier Naidoo

I love Fertig, Los!, and they were actually one of the reasons i started learning German. They have 2 albums out as of now, and each is different, If you want a more laternative sound, go with their first one, which is "das Herz ist eim Sammler", (I dont know what that means, i only started learning german a few months ago, and verty slowly at that) but if youlike more of a pop-rock sound like me, go with their second, which is "Plaene fuer die Zukunft" (sorry, no Umlauts on this keyboard ;D )

@dukepayen:

You're getting your Nenas mixed up.

Nina Hagen: http://en.wikipedia.org/wiki/Nina_Hagen

Nena and 99 Luftballons: http://en.wikipedia.org/wiki/Nena

I hope you mean that ironically. At least in the less mainstreamy music scenes people still normally buy CDs. I'd never pay for just the MP3s (except a band only sells their music digitally, and even then...).
I'd maybe call it 90s to buy vinyl btw, even though I can understand all these people that still do.

I like Philipp Poisel's music! Is there more artists like this one in german music scene?

@Konstantine

Well, thats a thing I cant really say..
There are many artists who sing songs like he does, with the same meaning etc. but everyone's unique I think!

I would say "Bakkushan" (with songs like ,Nur die Nacht' is a bit like Philipp, or bands like Jupiter Jones, Wir sind Helden..

@Sciera
Ich mag deine Auswahl an Bands..^^ Grad Ignis Fatuu z.B. ^^

Thanks!
