I love progress in technology towards simplicity. After Publix,
   I had a few minutes standing outside. With an app I found called
   ?#?PixiTracker? - I was able to easily make a little song
   without any effort. I've been waiting for something easy-to-use
   but sounds-good that gets the little song snippets out of my
   head from anywhere. I've tried other things through the years
   but none of them had proper ergonomics. In other words, they
   were complicated to understand and use. Took away from the "hey,
   I want to get this song out of my head real quick", which is
   something regular instruments let you do.
   Anyway, this worked well. In 10 minutes, just standing outside,
   I made a little song. It got a musical idea out of my head and
   into the world. Won't do anything more with it. I just wanted to
   capture it and share it. We're not quite at the level of "plug
   the computer in your brain" but this little tool helped me
   capture a musical idea in just a few minutes. Very happy. Waited
   decades for something that could do this in this way.
