I've got a fair few years on you and trust me age has plenty to do with it. As much as I can listen to new music it doesn't have same appeal as all the great rock I grew up with along with stuff like Radiohead, The National, Primal Scream etc. I'm no fan of hip hop, pop and electronic and you quite rightly highlight that this does reduce the appeal to me, which is exactly the point I was making. Just for your info the highlight for me on the bill is Idles. along with King Gizzard, Spiritulized, Code Orange, and possibly Caribou. If folks like yourself love it then I'm genuinely happy for you as that's what love music and festivals are all about and this is the right place to discuss these things.
