@ Nick Beat Hope you are feeling better!
@ Sniper Reload3d Thank you for your help.
I tried your suggestions, but still not seeing any of the CDLC files showing up. Only the ones I had before (bobmtre, elvisusp, funsome, jackiwan, outkheyy, traidrop). I added cherubrock to this directory (originally was in the 'Song Pack I' folder). I also got rid of the _p file (since I'm on a mac).
I now have cherubrock_m in the root folder and other _m songs in the 'Song Pack I' folders.
Still no CDLC songs are showing up. I'm guessing it is usually easier than this... Thank you for the help.
