When I wrote "Blame," I had the "I trust you feel the same" riff for over a month, then I realized the text "I trust you feel the same" matched the riff. A couple of days later I had the whole song.

It's not a great song, but it's mine and I enjoy listening to it. I'm making music right now in an attempt to create regardless of what people think about it. It feels like the opposite of comedy writing. I'm enjoying it and it doesn't require people.
