When I try to listen to the NSF version of MOON8 in foobar2000, only the first song in the NSF file will play. It should be able to play all the songs in NSF files.

I asked the creator if he'd release a version with one song per NSF file and this was his response:

Sorry, no. I'm not really interested in publishing extra NSFs to work around broken players. Please request that the player be fixed instead.

If you want to do it yourself you can use a hex editor to change the starting song in an NSF (it's the 8th byte, i.e. address 0007 in the file). Change 1 to 3 and it will start with track 3, etc.
I have a Samsung Galaxy Note8 running Android 8.0.0.
