Laufbahn literally translates to "career path" or "trajectory". It's an interesting word because it can refer to a professional career, but also more broadly to the course of one's life.
In the song, the artist reflects on his past, stating, "Das war keine gute Laufbahn" (That was not a good career path). This line hints at a difficult or troubled past, making the word particularly poignant as it encapsulates the journey from hardship to success, a central theme of the song.
Miksu / Macloud and t-low look back at how fast life changed once they got famous. They admit growing up wasn't easy and that some of the choices that got them here weren't good ones, but the hard years paid off.
Now the money is real: club nights, VIP tables, designer clothes, and enough cash to pay for anything. The song isn't only a celebration of that, though. It's honest about the cost too, including drugs and a wariness about the fake people who show up once you're on top, alongside real loyalty to the friends who were there before any of it.
The chorus keeps circling back to one idea: since the fame, everything looks different, but the person underneath is still the same one who used to stand outside the block in worn-out sneakers.
