Hmm, I don't know. I'm definitely a whole lot more alternative and indie now than I was back then. Undoubtedly. I listen to a lot of music I would never ever touch back when I was 13-16. I've always had an open mind when it comes to music, but I was definitely more "pop" back then.
I remember listening to a lot of Alicia Keys, Dido, Justin Timberlake and Alanis Morissette.
It's only natural to go through a change in your music taste, just like you change as a person as you get older. Personally, my taste grew along with my passion and interest for music. These days I listen to all sorts of things.
