David,

Thanks so much for the kind words.

In terms of the artwork, I use a variety of tools - mostly Keynote on my Mac. It enables me to incorporate a lot of graphics and lock in the dimensions of the object.

For SoundCloud images, just hover over the image you want to replace and you will see a button that says "Update Image" - use that feature to upload individual art to each song.
