Musings about Music

Is it an autistic thing to have a hugely varied taste in music, or do our tastes just diversify more as we get older? My own taste in music is very varied from heavy metal through 80's and 90's music to Trance music. For me it's not so much about the genre of the music but whether or not I like a particular song or the music to that song. Personally I like quite upbeat songs as opposed to the slower tracks, regardless of what type of music it is. What is other people's experience? What do you listen to? Do you tend to only listen to one category of music or do you prefer variety?
