multitrack sound files

[nibato]

I've been trying to setup subsonic to transcode NSF (NES Sound Format) files. I've made a command-line transcoder for them which works fine. However, the problem is each file contains multiple tracks, and only the file shows up in the library. Therefor, I can only make it stream one track per file.

I was wondering if there was a way I could either make these NSF files load as playlists, or show several songs per each file somehow. I'm not terribly familiar with how flexible subsonic is with mods/addons for this kind of thing.
