Continously playing music in a dungeon?

Did you notice how the selected song choice for the Returner's Hideout map(s) was set to (current song) in FF6LE, and might have wondered how it is playing the Returner's Hideout song at all then?

In many cases, a lot of the time throughout the game the songs that get played are handled by an entrance event code, this way you can have it play different songs at different times by using an event bit check. For instance during the Returner's Hideout, it has the song Awakening play instead for a while... When it is set to (current song) in LE, that's what's going on.

With most of the actual dungeons, the song is set to play on the map in the LE because there is no need to continuously play any other song.

But when a song is being set to play via the entrance event & bit, and the map is set to play a different song instead of the current one, it will be interrupted at first for a split second by the entrance event song which is loaded right before the map, which causes the map set song to be interrupted and start over.

You can see in FF6LE the entrance event for the Returner's Hideout maps (3 in total) and they are the same, set to F94E (CA/F94E)
So looking in the event dump:

CA/F94E: C0 If ($1E80($1B6) [$1EB6, bit 6] is set), branch to $CA5EB3 (simply returns)
CA/F954: C1 If ($1E80($012) [$1E82, bit 2] is clear) or ($1E80($25E) [$1ECB, bit 6] is set), branch to $CAF95F
CA/F95C: F0 Play song 5 (Awakening), (high bit clear), full volume
CA/F95E: FE Return

CA/F95F: F0 Play song 46 (Returners), (high bit clear), full volume
CA/F961: FE Return

So anyways, you would want to change that F0 46 to F0 17 for it to play Mines of Narshe. And be sure and put the song back to current in the LE, if you intend to keep it like it was in the original with the song changes.
