Hi guys! The GBS format supports multiple songs (from the Game Boy) in one .gbs
file. See [1] for an example file. I've checked the git code [2], and even
though the game-music-emu library supports playback and querying info about
multiple songs in one file (via gme_track_count() and gme_start_track()), track
0 (first track of file) is hardcoded, thus ignoring any other tracks in the
same file.

I would write the patch myself, but I don't know the GStreamer API well enough,
I'm only familiar with the game-music-emu API. I've seen an article [3] about
streamids, so I know this should be possible. If someone can hint to where I
can look in the code, maybe a similar plugin that supports multiple tracks, or
the API headers, I can make a patch.
