Not everything is melodyned these days. Some artists still have talent. You can tell when they perform it live no problem that they're not using software to cover up their mediocrity. Prince is still around, John Legend, Marsha Ambrosius and Alicia Keys, Cee Lo Green, Ne-Yo. There are many others.
I'm sort of tired of this assumption that basically that's all music is these days, when it's not true although the mainstream promotes that. Why do you think that is? I think it's to distract people from the good music that's out there these days that can make positive change like Michael Jackson's music. They don't want music like that promoted, actual good music that is pushing the boundaries in a GOOD way and makes us think positively. They want cheap knock-offs that promote sexuality, partying, immaturity, etc. So for the most part they keep the good music off the radio.
I think they also realized the effect that music had on people in the 60's-80's and they have been trying to be more in control of that, because from the Beatles to Michael Jackson, worldwide hysteria was being caused by their messages for global peace and just their motivating encouragement was getting people to think for themselves and be better people. I think that they just want people to mindlessly go to work, feed their children, maybe have some sex with your wife, go to sleep, and do that again every day.
I don't think the people who are running the show really want people like John Lennon and Michael Jackson, artists that can make a difference, having much of a voice on the radio too much.
