music is part of my routine....I can't leave the house without my mp3. I actually get really anxious and uncomfortable if I don't have it with me. Sometimes my headphones snag on something or I drop my mp3 and my headphones get pulled out of my ears. This for some reason, is excruciating for me. The interuption of a song I like, even for a few seconds, can piss me off so much I can't move for like 10 seconds. It's helps me concentrate also. Lately when I've been drawing, I've been putting the same song on repeat for up to 4 1/2 hours at a time. Also, I'm synethesiac. When I hear music I involuntarily visualize colors, shapes, textures, and patterns. It's actually quite rare for someone on the spectrum (1 in 10,000). For NT's though 1 in 23 are synethesiac. So to answer your question, yes music is a very big part of my life and it can be theraputic or cause small meltdowns. Go figure.
