When listening to music, what style/artists/songs really get you thinking, "Wow, that was really clever." Here's my example: Progressive Metal. I bought a Fates Warning CD. They are along the lines of Dream Theater. For reference, it's the pleasant shade of grey album. It seemed every minute, I was shocked with something new and interesting. Though I don't play progressive metal (not good enough) I really hope to draw some influence from this fantastic genre. Also classical music... I really enjoy preludes and fugues... a lot of Baroque stuff. Preludes especially... just really cool complex stuff.
