too impatient to wait for gid to fix this so I wrote a little program to play the song here.

in case someone wondering, the program I wrote did not make jpcsp play the song, the program play the song itself, and it did not play the song using files from the ISO either, it play the song from it own files.
and I wouldn't call this perfect solution for the problem since I just started to learn programming so the program sometimes play the wrong song or play the song before the loading done.
anyway, while playing the game, I notice some other problem here:
1. The video play slightly slower than it real speed (even when not recording) so the dance become more and more desync with the song.
2. the video have 2 video streams, the star you see mid-song is suppose to switch between them. as r2810 added support for MPEG video having multiple video streams, instead of switching like it should be, jpcsp randomly chose 1 stream and play it from start to end and not switching it mid-song at all, you can see it in the second song I played in the video.
3. the preview sound for the songs is always the preview of the first song.
those 3 problems are not as gamebreaking as the no sound problem but could cause some annoyance, though if possible, please fix the sound first.
