I am a child of the 90s too. I rarely listened to the Beatles growing up, but as I grew older my tastes expanded. I've discovered Miles Davis, Julian Lage, classical music, and, yes, the Beatles, among many other artists from assorted genres and eras. There's nothing wrong with loving grunge (I do). But, personally, I would find it depressing to listen to the same thing for 30 years. To me, that'd be like never going farther than 50 miles from your hometown for 30 years. Not a judgement, as we like what we like, and I understand that there's comfort in familiarity. You only get to experience life once, so it makes sense to me to cast a wide net and absorb as much as you can, while you can.
