Change a song at X seconds during a Battle

[NatuElChido]

Hello everyone, I'll be doing this quick, because I'm almost sure this has been asked before, but I haven't find a solution to this or at least, a thread that talks of this topic.
You see, I want to skip the battle assigned song after 30 seconds has passed, because said song has a 30 seconds long intro, so I don't wanna listen that intro again during battle, but ratter the rest of the song without the intro, and that that song is what it will loop during battle.
As an example, I want to make something like:

Spoiler

Like Porky Means Bussiness, if you are familiar with Eartbound, that have a ratter calm intro then, it go crazy, and only the crazy part loops during battle.

I'll be very thankfull if you can help me resolve this issue.
Thanks.

If the first 30 seconds is just an intro, why don't you paste the two tracks together with audio editing software and have the thing loop from the 30 second mark?

Himeworks had a plugin for looping songs like Jules describes. I don't know if the site is going to be back up any time soon though. Here's a link, because you never know:

Maybe, but the think is the battle is desing to be long, maybe 10 mins, so maybe I would actually repeat the song eventually, but if i don't come with another solution, I'll be doing this.
