Yes, everyone has different music tastes. Do not feel inferior or outdated because of the genre of music you like. It's perfectly normal and I think only a cultured artistic person while find joy in listening to music besides the songs people are singing now. The music of the 80's is beautiful and it is perfectly normal to listen to it despite the fact that we're in 2015. I'm 13 and as young as I am, I still listen to 90's music, I have never really seen anything abnormal about that, maybe my taste in music is unique compared to that of my peers and maybe the same goes for you. So keep listening, as long you love it and listen to it out of your own free will.
