i listen to whatever music i think is good, be it modern or old. Oldest artists I listen to are frank Sinatra, bob dylan, marty robbins, beatles, beach boys. newest are kendrick, kanye, run the jewels, death grips. refusing to listen to new music just cus it's mainstream is stupid. lots of newer artists do it better than the older ones, like royal republic (amazing punk rock), royal blood (amazing hard rock), kanye (easily the best overall rap music), iron and wine (amazing folk music), galneryus (amazing power metal), and many other examples. Of course I'm not bashing the classics though, just saying you shouldn't limit yourself to just the oldies and underground shit.
