If by "music today" you mean "modern pop music", then... yeah, modern pop music sucks. You're not old; you just have taste.
Really, I have no idea why modern pop music is as awful as it is, but it's usually like a goat being shot, but it clings dearly to life, bleeting and chewing its own mangled jaw, just never dying. That's kind of life pop music. Today. Except that was an awful analogy.
Besides, is being "Old" bad? What are you seriously missing out on? What mathematically produced, auto-tuned, uncultured, boring garbage by a filthy spoiled pig are you really, really feeling that you are missing out on?
Who needs rock and roll, swing, grunge, or 00's dance when you have, Will Pharlell and Iggy Azalea or One Dire... pfft, hahaha... I couldn't even type that without physically laughing, which I am now communicating to you through text. Isn't technology amazing? Yes. Is modern music? No, oh God no. So really, what are you missing out on? If those teenagers and young adults now a days don't want to experience the good old days (read: seven years ago. It's a YouTube search away, kids!) then just let them fester in their garbage and regret it, knowing that they were the lowest common denominator that they are complaining about in the winter of their life?
Really, that's much more cruel and much more deliciously evil than taking away their shitty rave music. Let them suffer, but not until they need support and entertainment the most. Such gleeful schadenfreude.
