Tested out the Looping Ending 3 patch, and noticed something while aimlessly listening to that awesome track for awhile:
After about three full loops (probably 3-5+ minutes listening to it at least)
I notice a "wahhhhhhhhh" effect from a Strings 1 sounding instrument begins playing until a different song is played. This noise continues if the music is faded out during an event (but will stop if sound effects are played: The sound effects from the "Airships Bombing Damcyan" visual, for example, cancels out this odd side effect).
Note that it doesn't really hurt anything. It doesn't cause the "Oregon Trail just raped my sound effects" problem I get when playing "Ending 1" then entering a battle lol.
