Can i change back to my old ways?

It started when I was about 14 i started listening to all the bubblegum pop that kids listened to. Jesse McCartney, Brittney Spears, NSYNC, etc. Then when I was 16 i started liking this country singer. And i started liking this other looser who sung R&B music. And now I cant go back to what I use to like. Now im 18. And i put myself on a pop music break during that time. And now i cant even stand to listen to Top 20 radio. It makes my ears ring and I end up yellin at someone to turn it off. Cause nowdays all those artists use autotune. I dont understand the whole Bieber worshipping and Lady Gaga bowing and crap. I cant go to that side. I honestly feel like im growing up too fast..for my past 3 years I have liked nothing but men in their late 20's to mid 30's. I cant even look at a guy my age now. I guess im just growing up faster? I want to keep up with the teenagers but I guess the singers my age and stuff dont sing anymore and now Bieber and this Cody Simpson person I have heard about are the new generation. It makes me sick to look at Disney Channel and Nickeloden. I use to love those channels. Now the only show I will watch is The Voice( im #teamblake btw) and One Life to Live which is bein taken off =/ But anyways can I ever switch back to my old roots? I never feel like going outside anymore or doing stuff that I use to do 5 and 6 years ago. HELP! =/
