Greetings from Germany – He’s singing about how he’s going to tear everything down (in many many metaphores) and how “alles” (=everything) is gonna be “neu” (=new). Chorus:
“Hey, alles glänzt, so schön neu.
Hey, wenn’s dir nicht gefällt, mach neu. (Hou…)
Die Welt mit Staub bedeckt, doch ich will sehn wo’s hingeht.
Steig auf den Berg aus Dreck, weil oben frischer Wind weht.
Hey, alles glänzt, so schön neu.”

Translation:
Hey, everything is shiny, so pretty and new.
Hey, if you don’t like it, make it new/renew it.
The world is covered with dust, but I wanna see where everything is headed/where everything is going.
Climb on that mountain of dirt because there will be fresh air up there.
Hey, everything is shiny, so pretty and new.

He’s actually pretty popular in Germany everyone likes him because he combines really catchy melodies with nice visually strong lyrics. I’m not his biggest fan but I can appreciate it!

P.S.: Love your blog!
