I think I miss out on a lot. I do admire the skills of so many wonderful current players. I have great respect for them. But as much as I love music, I do not keep up with much current stuff. I still have a lot of (non-uke-related) new wave, punk rock and other things from my younger days, I like some classical music (including modern/avant-garde sorts of things), some 50s-60s jazz and really a pretty wide variety of music, but the bulk of my listening is older music...for some time my listening/collecting habits concern pre-World War II recordings. Old rural blues, 1920s-30s country stringband and folk music, a lot of early recordings of ethnic or "world" music, vaudeville and British music hall type of things as well as early American popular music circa 1890-1920.
Again, while I admire and respect the skill and even enjoy watching such things on Youtube, etc. (and I try to learn from EVERYTHING) I am just not personally too interested in people who do, say, Beatles songs on the uke or do modern pop sorts of things. There's nothing wrong with it, and I understand the appeal. It just holds little interest for me as a listener or player. Although I try to remain open to everything. I don't automatically shut out anything.
In short, I might like to listen to some Nirvana or Radiohead now and then, but you won't find me trying to play Smells Like Teen Spirit or Creep on the ukulele. I leave that to others who could pull it off much better than I ever could. I think a lot of that stuff is fun to see and hear now and then, but because it's so much not "my thing" I am sure I miss out on a lot of great players who innovate and do great things, whereas I'd rather just do my little renditions of "Got A Date With An Angel" or "Ain't Misbehavin'" or whatever. All that may have been done scores of times, but it's what I like and where my heart lies.
