I have been listing to the All Songs Considered podcast this morning, probably the most eclectic of the music podcasts I follow. So far I this morning have listened to a show of nothing but electronic music and a couple of surf/punk concerts; last week it was a bollywood dance band. In the past they have played concerts by Weird Al Yankovic, Richard Thompson, Los Lobos and tons of other artists I have never heard of. I haven't liked everything I have heard but my ears have been opened to so many more things that there is no way that I can listen to all the new things that I like.
New things are generally good. It doesn't matter if the things are food, music, friends, movies or experiences. I am not saying go out and shoot herion or get whipped in public if these things are bad for you. But if someone asks you if you want to eat a chicken foot or you should listen to this new band, giving it a try can't hurt you much and something good might come out of it.
