.sng Player?

When you unpack a rom you can find the music in .sng files. How can I play this type of music files? I really want to play the songs, but when I don't know how to do, I have to ask. If this is not allowed here(I mean if I'm not allowed to talk about this) then just(please!) lock the thread. Don't say too much about it, just lock the thread if it's NOT allowed.
