So I just recently bought My God Is The Sun by Queens of the Stone Age from the DLC store and when I went to play the song for the first time I noticed that all my QOTSA CLDC was no longer in the song list even though the files are still in my dlc folder. I downloaded the files again from the database but they still don't show up in-game. Don't have this problem with CDLC of songs by other artists, just QOTSA.

Take RS Toolkit and import the songs. Look if they share the same "DLC name". It's the first field within the "Song Information" group.

 

If the "DLC names" are different, look for all arrangements. Select arrangement, click on "Edit". If two arrangements share the same "Arrangement Identification", the song won't be displayed either.

 

HTH

This has happened to me with dlc not showing up, try launching from Uplay?

The DLC names and Arrangement IDs are both different for the songs...

 

EDIT: Changed the package ID from Cherub Rock to My God is the Sun on the missing CLDC and they seem to be working now.
