BGA sometimes stops playing early or doesn't stop playing

This seems like an issue when using with pop'n music, but also anecdotally happened when used on iidx.

testing around with this i can confirm the bug where long sounds (system BGM left on for a while usually, maybe 5~ mins?) cut out. made me think the sound engine died at first but it's just the song. other sound effects work and on switching screens/songs it comes back

I’ve also noticed sometimes the song preview and the system bgm end up playing at the same time; not sure if it’s from hypersonik

i think its the first song you hover over after playing a song if im not mistaken

I'm able to reproduce it like so:

1. Go into pop'n Jam and Fizz song select
2. Hover over a song and listen to song preview.
3. Wait for the song preview to end and for the menu BGA to start playing.
   • Sometimes the menu BGA won't loop and instead stops.
4. Move up/down to select a different song: both the song's preview and the menu BGA will be playing.
5. Move up/down again, while the song preview is still playing: the menu BGA will stop (as expected).

@bicarus-dev Do you have any insight on what kind of issue would cause this? It's a weird issue, since with the same sound clip, the first "call" to stop it doesn't work, but the next time it's called it does work.
