[PROBLEM] CUE + Monkey Audio files

[Tim Curtis]

I have checked the permissions and they are 755. Also, all the files have the same permissions, the APE+CUE, the FLACs, etc. Also, I have moved it to a USB stick and regenerated the DB and same result.

Very odd.

Maybe the cue file contains some binary characters which are causing some sort of issue with MPD parsing the file. They won't show up in an editor unless it has a "Show invisible characters" option. 

You could try the Linux "file" command. It will analyze the file and print a status that can indicate whether binary data was found in a text file.
