Song meaning of Was weißt du schon by Apache 207

Okay, okay, okay. So, "Was weißt du schon" by Apache 207 is about rats, dreams, and block life. Apparently, rats are just chewing through walls like it's their day job. And let's be honest, they were probably born there like the rest of the block, but they don't seem too keen on staying either. Mama, don't worry about the white dust on the ceiling, it's just some paint chips falling off. It's nothing compared to the other things you might find in the hood. Meanwhile, the singer is trying to ignore his vibrating phone because he knows the girl on the other line is tryna get with him, but he's not trying to deal with that drama. He's busy dreaming of driving a Caddy or a Chevy, but he knows those dreams are gonna drown in a bottle of Jack Daniel's like every other night. The block life might be tough, but there's always a glimmer of hope, like catching a glimpse of a shooting star. Even if you follow the wrong path, at least you're trying to make your way out. But what do you know about all this? You probably grew up in one of those fancy neighborhoods where the rats wear bowties and sip tea.
