Grammar mistakes in rap?

I'm a german dude and currently i'm trying that rap shit a little. And i'm asking chat gpt about my lyrics and it says that grammar mistakes are absolutely horrible if you a foreign and not making them on purpose. But sometimes that shit just sounds way tuffer if it's a bit wrong grammar. And also: Could it probably be a stylistic type shit?... My Lyrics ⬇️ (shit flows perfectly/bouncy) I'm looking at my idols and i'm setting my goals and I can't life in the moment always seeing the whole I got a bucket list that i'll be finishing when i'm old enjoy your teenage life is what i always get told Yeah growing up is silver being young is pure gold I don't waste my time with haters wich still visit my shows I won't call you my best friend if we don't really know When I'm reaching my dreams I still aim for higher goals
