lol I have changes in Music I like too. I still like the old bands I used to listen to but I just don't listen to them that much, it's not like I hate them now.
Here's my change: I started off liking rap, then went to Metal, then Metalcore, then Hardcore and Screamo, then Deathcore, and now I like all Metalcore, Hardcore, Screamo, and Deathcore. I still listen to some of those Metal bands I used to listen to that I don't listen to as much though, which are Slipknot, System of a Down, Lamb of God, Mudvayne, and Mushroomhead. System of a Down was the band that got me into Metal, Lamb of God got me into Metalcore, The Devil Wears Prada got me into Hardcore, Bless the Fall got me into Screamo, and Bring me the Horizon got me into Deathcore. I still listen to Slipknot a little bit, but I'm starting to realized that their lack in musical talent, such as them having a really bad guitar riff in most of their songs, but other than that they're good.
