The major difference IMO between today's music and old school music is the lack of love songs: love for ourselves, our significant others, our family and friends, and one another. The musical content was just as ratchet with old school music, but they also had a plethora of love songs and political/social awareness songs promoting positivity and pride.
Nowadays, artists seem afraid to produce conscious music because they think it won't get played. Good love songs come around, but they are far and few. The main difference is really in the way my generation (80s baby ~.-) utilizes their social influence: old school artists seemed to be a bit more philanthropic and actively participant in uplifting less fortunate communities. Today's artists seem to be more self-centered, sexist and flashy with their wealth- as opposed to sharing knowledge that would help empower our race. I am not racist, but I do feel we should stick up for one another more. Instead, we thrive on tearing each other down; but that is another conversation that will have to be discussed later.
What pisses me off about all of this is the way some older people turn their noses up at new school music as if its all just pure garbage because we've lost our way and don't live by their old school values and morals. Bitch, your old ass is just a retired Rihanna: don't front. We learned everything we know from YOU: what did you expect?! I know we are straying farther away from the days where everyone remained virgins until they were married, but don't act like were all satanists. GTFOHWTBS.
