As a German I basically have an endless stream of music to share, but nothing really stands out spontaneously that's worth sharing here... but I'm sure I'm just not digging deep enough right now. Only one thing came right to my mind, our wedding song. It's from a band called Silbermond (and obviously very, very cheesy, so I will spare you from any lyrics :D)
Another Silbermond song. I don't think you don't need to understand German to get chills from her voice:
Her voice is exceptionally good! And she's also very, very good live.
I listen to very little German music, especially in German. Since I'm a native, it can reach deeper in my heart, but it has to be really, really well done for that with a lot of feeling (and mostly cheesy).
Listening to YouTube stuff right now, to find something else worth sharing.
Remembering German punk bands!
One of my favorite songs from an authentic German punk band WIZO (Lyrics)
Also, everyone who has the slightest idea of music in Germany should probably know Die Toten Hosen (Lyrics). Great good mood song! But they also have a lot of very good older stuff.
This is one of their most recent songs. But basically every German knows them and they have a very good reputation.
Another one of my top 2015 tracks (synth pop) (in English, though, but a German artist that was casted in a show and won the Eurovision Song Contest):
Honorable mention goes to Blind Guardian.. not really representing German music, but one of my favorite German band :)

This one also contains some classics: https://www.youtube.com/playlist?list=PL5219C5FC3806FEA9
Well, there are surely a looooot of good songs missing as well as a lot of mandatory classics, but I think I got quite a good collection there to give you some intro to the German music. If you have specific genre requests, I can see what I can do :)
