i have to agree with you. Rappers used to pride themselves in intensity and ambition. Now it's all about who is the biggest fckup.
also the image they sold back then cannot be done today. We see these guys tweeting and sharing and realize they're normal idiots like everyone else. Back then, rap (like most styles of music) could markets its stars as living some aloof, amazing lifestyle. Now we see them tweeting as they take shits.
