When i have a corrupted profile, i simply go to my profile folder and right click properties on both files, click on the tab Previous version and i restore the last working version. But, of course, a backup of your profile (and your cdlc's) on an external drive is always better.
Personnally, i don't like it, i think it's more difficult with DD (i know it's ridiculous). But i would never ask to remove it, i know that many people like it and of course, it's a must for a beginner.
NonStop Play doesn't have random shuffle, you can choose the songs you want to play. Maybe you are talking about Rocksmith 1. For your information and probably your great pleasure, The Dark side of the moon has been charted in a one big cdlc. http://customsforge.com/page/customsforge_rs_2014_cdlc.html/_/pc-enabled-rs-2014-cdlc/the-dark-side-of-the-moon-r79
