@milady133: I just tried it on a device where I run the live wallpaper app Multipicture Live. That app lets you specify a single file for the lock screen background as well as for the various home screens. I set up CC to save the cover in /sdcard/Pictures/cover.jpg (/sdcard is the device's internal memory). I then told Multipicture Live to use that file as the lock screen background and also to redisplay the image if the file changes, and for good measure to reduce the opacity to 60%. Works perfectly.
