Hey that's a good thing. The best music was made back then.
That's not alltogether the truth, and nothing but the truth. It's entirely a matter of taste.
There is great music being made now, some of it derivative of what was made then. Some of it is updating the sound of an Ella Fitzgerald song. Verve put out 3 remix CDs with new mixes of Jazz standards. Some of the mixes are forgetable, but some are fantastic.
I've enjoyed watching my taste evolve as music has evolved. In HS, I got hooked on "New Wave", which progress to "early '80s"--cornball, dance sheesh that I would never listen to now. By my latter years of college, I started to find my identity through "alternative rock," namely, The Smiths/Morrissey and REM: lyrics you really identifies with, "Hey, this song is about my life!" By the early 1990s, I was into grunge, which is a subcategory of alternative. Today, the genre is the same but the angst is gone. I like Modest Mouse for their intelligent wordplay. Beck, Kings of Leon (southern twang, good times music), Foo Fighters (rockers) and Interpol (Joy Division spawn, circa 1979).
I scratch myself when I hear others say music

with The Beatles or Pink Floyd. I know what they listen to. I can't help but think what they are missing out on.
There's that...and the fact that it makes it difficult to enjoy live music.
