How can I like new music? I love Rolling Stones, CCR, i.e. clic rock, but can't get into anything post 1995

My friends make fun of me because I hate the sound of most new music. I like a wide variety of old music... Stones, ELO, Bowie, Queen, Eddie Money, Pink Floyd, most everything before 1995 and NO new bands after like 2000. Why is this? Is it mental with me already? I'm only 21. I even love rap... but older rap when it wasn't so pop... what's WRONG? What do I do to find new music that works for me?
