I remember listening to the radio as a kid and finding that the songs always made me feel more peaceful. Funny, but the more hurtin' the music was, the better it made me feel. I think of that now when I write my songs. I may not be feelin' the blues myself, but I'm writing them for other people who have a hard life.
I do most of my vocals - aside from a couple of little one-shot vocal samples. I record everything into the Saffire with an SM58 then scratch it with loads of plug-ins. I don't do much vocoding to be honest. All my vocals are usually done with Melodyne and a ton of other plug-ins to make it sound weird.
