This might be a loaded question, lol, sooo...
Traditionally, I like alternative / rock from all eras, although im probably most familiar with the late 90's - 10's. With some typical pop and hip hop-ish stuff sprinkled in.
A few years back i started getting frustrated with, what i percieved, as a lack of everything. Simple beats, dumbed down lyrics, grating voices... i got snobby. It got to the point where everything new comming out, was actually annoying me. I figured if it had to lack substance, at least it could have a good beat. So, i ended up listening to alot of electronic music. I'm pretty up to date with dance and house now.
Really, I'm good with most genres, save country, classical, and jazz. Although, some "country" from the early 00's can be ok. More popular Keith Urban or Kenney Chesney songs are fine, although, i guess i consider that more pop crossover.
I used to be up on all the new music and go to all the shows, but the shows stopped after marrage and my snobby self has fallen behind with the new music, although I recently discovered free vevo and xite with my Samsung TV and I've been impressed enough with some of the newer stuff to want to maybe give it another go.
It's almost like you started reading this Time Article but never finished.

While the consensus is out about whether or not or attention spans are really shortening, most sources say whatever is going on, isn't permanent...yet.
We still have the ability to unplug and find something that's truly interesting to us, something that we care about, and focus on it. We just have to find it, and then, actually do it.
