I think that justifies for some child abuse right there. That's absolutely TERRIBLE.
I won't go and say there is no good music. There is. However, things certainly are changing constantly in the music biz. First, rap blew up. Everyone wanting to jump on the boat, and artists couldn't come up with anything original, so they started just doing remakes and samples of older music. That got old, and they started making shit like what you posted above. There is no creativity in that genre. I've also noticed there is no shelf life. People will go crazy about a song for about 3 weeks, at which point that artist is completely forgotten.
Theres also issues with the labels not doing shit for artists any more which is keeping artists from growing and coming out with multiple albums, now everyone is a one hit wonder. This creates a need to go over the top for that one song, grab everyones attention, because you know thats all you will ever have.
I've started listening to a lot of country. It's changed in the last five years, it's become younger and far more upbeat and positive. The songs are fun. I grew out of hard rock/metal for the most part, just got tired of it. I say this as I'm listening to Killswitch Engage screaming, lol.
