As far as I can tell from the screen shot you attached and your playlist everything looks good. The fact that ‘Ghost’ cannot be played even if you select it directly means that there is something wrong with the song itself, not with the playlist. The folder shouldn’t have a different symbol then the othe two…
Please check the following:
– do all wave files have the same sample rate and bit depth?
– are all wave files mono?
– are there any hidden files in the folder that holds the ‘Ghost’ files? (please make sure that you have the latest firmware Version 83859… the hidden file thing shouldn’t be an issue in this firmware anymore)
Hope that helps,
