I hear you on the music being first. I once thought quite hard about it, and then finally I had to admit to myself that I can live without music (albeit very miserably), but life simply would be of a far lesser quality if I couldn't write.

Writing down the thoughts... I do that a lot, too. I even have a mic for the iPod in case I can't write, like when I'm driving. I'm not obsessed or anything, really. LOL :)
