I don't know how old you guys are, but trust me, it's only going to accelerate into complete Idiocracy and musical tone deafness [if not outright deafness] as the current teens and 20-something kids start to dominate things.
Right now you're probably playing that John Williams fare for post-Boomers, born circa 1975-1985 [currently 30-something Middle Class concert goers], who can vaguely remember those tunes from their childhood.
And even the Boomers have crap for taste in music [how many times can you play "Eleanor Rigby" without losing your lunch?], but the kids nowadays listen solely to Gangsta Rap involving "twerking" soft-core porn actresses, like Miley Cyrus.
[And stay tuned for the "oops" hard-core porn Miley Cyrus video - her iPhone will get "hacked" and the intimate wedding night video will be "stolen" and uploaded to pirate websites, just as soon as she can no longer go Platinum on a regular basis, and she needs to reinvigorate her career with a large dose of celebrity heroin.]
Fear for the future of the Human Race.
You simply cannot misunderestimate how bad things are going to become.
