@@HighSolstice Strangely, some of your songs listed in your post worked for me (the names and the versions are the same). I made another repair with only the corrupted CDLC, only one was repaired, the other stay broken. :( So try another repair with only your corrupt CDLC, maybe some of them will work.
@MrFluff3h Try this: In your Steam library, right click on Rocksmith 2014 Edition Remastered > Properties > Local files > Verify Integrity of game cache... Sometimes Steam find an error and fix the broken file(s). Hopefully it will help you!
