Speaking in the synesthesia sense, listening to Arcade Fire's Neon Bible is an incredible experience.

So many layers, depths, colors, and shapes. It's quite beautiful.

"Sleepyhead" by Passion Pit

When I hear music, I also see a picture. In my mind there are shapes, colors, and patterns. I'm doing my best to recreate these images.

This is roughly what I see when I hear the song "Sleepyhead" by Passion Pit. I've included the song so you can take a listen.
