Lupe Fiasco is a hip hop artist I like. But his lyrics include things like
"'Raris too expensive and they way too hard to maintain
Get yourself a Camry, "nigga said a Camry?"
Watch that ho depreciate and then you'll understand me
It's called being fiscally responsible"
But I do have to say I don't listen to most hip-hop/rap. Also for songs that are about anti-mustachian behaviors, The Distance by Cake is all about the guy who loses his family because he spends all his time at work focusing on building his career.
