I have an  issue where some CLDC's do not show in the game but are in the DLC forder and of the correct type.

An example was  "One love people get ready" It did play before.

The only way I could fix this was to delete the song and re download but with the amount of songs I have I only find out the song is not showing when it pops into my head and want to improve.

I have CSM and run a full repair but no joy.

Is there an easy way to check for others not showing without simply writing down my DLC list and cross referencing the in game list 

Probably due to the fact that you have chosen a selection filter.

For example display only favorite songs or in different order.

 

Check these points and let us know here.

No selections ticked and it only seems to be a very small amount 

Apart from a bad ID (cherub rock) or a bad placement folder, I do not see why it does not work.

 

Have you converted to another platform?
