It's not getting worse :/ For me, I find that the celebrities that are most popular like 1D justin bieber nicki minaj e.t.c are shit and make my ear bleed, but i can't be bothered to go round purposely hating on them. but there are really good bands that are new, like Foster The People and noah and the whale.
this is my hypothesis
good bands start off small, maybe one single getting in to the top 20 and the get better with time and experience and 10 years later, they are the biggest band in the world.
people who get famous straight away are usually bad and people will forget about them in at most 4 years.
so i say wait, be patient it will get better
(and Im a sucker for soft rock)
