Yes, nice post Simao, and like Almarg, there is no hesitation when I hear something I don't like as I just hit the other preset. We vote with our wallets, feet and fingers.
Something alluded to but not fully fleshed out is that as I grow older, I find myself less tolerant of what I consider bad music. I think it's one of those rights I think I've "earned" having been here long enough on this mortal coil. Expressing that right is generally tolerated by society as I can be thought of as "that old codger", or something along those lines.
People have become aware that music can be nothing more than an extension of one's personality and there are some pretty rotten people out there with attitudes up the ying yang. It's like the guy with the pit bull at the park who lets his dog jump at you only to restrain it when needed, or the fool who comes up next to you at the stop light with his personality blasting out the window, complete with the "I don't care what you think" expression. Music has taken a turn for the worse as this is the kind of popular music being marketed nowadays. Who wouldn't bemoan it?
Great and wonderful music exists and there's more out there than I can listen to but when just about every kind of contraption out there is capable of transmitting peoples personalities, invading my personal space, it becomes annoying, which I think is behind the OPs post. Boundaries are being crossed and respect is not a consideration. Cell phones are propped on desks playing music I never asked to listen to and people are singing loud enough with their headphones on to be a nuisance.
So, yes, some new music can and does suck.
All the best,
Nonoise
