I do think music and personality do work together.
I love music in general and like all genres but lately I've been into epic music. Trance and indie are right behind. I've always been into music that had a bit of epicness to them. For instance, I'm mostly drawn to Ryan Farish's songs with am epic feel to them ("Sing to You" was what got me hooked on him) even though he isn't an epic composer, there's a bit of it in some of his stuff. His last album, Bloom, has that epic feel too.
When I was in high school (about 20 years ago!), I would listen to this one tape over and over again where the base was so awesome (or so I thought) with some epicness to it. If I could remember what those songs were called, I'd youtube them and post them. Hope I can find them someday.
I'm drawn to music with an epic feel because I love to imagine things outside of reality...thin gs like life after an apocalypse, new worlds, underworlds, parallel worlds, etc. Just worlds outside of earth with advance technology, etc. It's my way of dealing with reality and a tool I've learned to utilized to my advantage growing up so that I can escape the hardships of things that were difficult to understand or deal with. It's become a part of me.
