Your eyes are closed if you haven't noticed a massive difference between the years of Elvis and today.
I think your responses have made my point way more eloquently than I could do myself, so I guess I'll leave it here.
I urge you to consider that fitting into the culture isn't worth it if the culture is bad. You may not see the culture's taste in music as bad, which is fair, but I am sure in other cultures (say in highly restrictive and conservative cultures) you'd be ashamed to be culturally literate (antebellum south? Jim Crow era?).
