I agree with you as far as NYC old heads not having growth but, I don't agree with the youth being the ones to bring the change. In reality it's two things happening. Whoever plays the songs, are deciding what gets played based on money, and trying to be the first to have a song. Then its the people who own labels. They are the ones who will let what gets to the masses and what doesn't. Most of these people are older people. The truth is most of the music that is popular now, is not new in style, and has been done before. Its just people who decide what gets shown to the masses want a quick buck, so they choose artists who have music that they can make money off of.
The more "******ish" the artist is, the more love they get from young people because these artists personify that "i don't give a fukk about shyt" attitude. Most young people are not political, thinking about sex and being safe, not being drug addicts,etc. They just want to get fukked up, and fukk anything moving, and get money. They don't see the after effects of living like this, and don't want to hear it. Its called being young, and ignorant, we all went through it. The difference is now, none of the consequences are being spoken, and everything is about enjoying yourself, and do what you want. The artists who are pushed are the people who personify this mind state, and they happen to be young. This is really why the music sounds the way it does now, its easier to sell. I was watching the ASAP Rocky documentary, and he said he's proud to be a ******. Yet, I don't think he really knew what he was saying. I love ASAP Rocky, and his crew, but I understand why they are being pushed, they don't have anything to say besides "let's feel good", and they help keep that "******ish" image going. But, in 5 years his company will find a new ****** next year. That is the sad part about these young rappers who just rap the "fun life". Because they are a dime a dozen, once their record companies get their money recouped, they get rid of them, and find a new ******, because that is the name of the game. Keep bringing in new "talent", and keep robbing them since they just want to have fun. The longer they stay in the business the more they realize there is more to life then partying, and then they question whats happening, then want to rap about it but, by then they are kicked to the curb. The company found a new ****** to hype uo, and the "fans" think the other guy is "OLD", and played out.
