No, you're not alone, and what life requires of people at different stages doesn't lend itself to the process of staying current with music that's designed to speak to issues we don't face in the same way. Plus, you reference some of the great popular music of the last 100 years. That said, lifelong learning and accepting of new information and patterns is helpful in avoiding stagnation and decline. It's one of the attractive factors in this sort of forum. To aid in this, one might choose to look at other musics on purpose, educating one's self about the issues of the times. I heard AM radio as a child, unformatted. One could hear jazz and blues from the 20s, live dance music from Tommy Dorsey or Count Basie, Texas swing from Bob Wills or Hank Thompson, Hank Williams live from Shreveport on the Hayride, the NBC Orchestra under Toscanini; Bill Monroe, the Osborne Brothers and others creating bluegrass, on into rockabilly, rock and roll, doo-wop, Mo-Town, British invasion....... Oh, MILLS BROTHERS.

Continue to enjoy the music that speaks to you, but it might be relevant to learn to speak to other styles, learn to play them, or whatever. Time, I know, is an issue. The apparent slow period in quality new music is no
reason to ossify. If you don't care for what's happening now, there's plenty in other directions.
