// @version     why did i have to update this again
// @description Adds your own custom music for PS by replacing the preloadBGM script.
//              Note that the music selection is entirely up to you; I provided examples so you get the jist of it.

//              you will probably want to replace that with whatever servers you're using it on
// @grant       none

//The above code can be edited. Go nuts.
//A note for all of you people who are like "wtf is this code":
//BattleSound.loadBgm('url', loopstart, loopend):
//	url is the url of your music. NOTE THAT THIS IS THE URL OF THE FILE ITSELF, NOT THE WEBSITE THAT HOSTS IT.
//	loopstart is the start point of your loop (If I'm not mistaken this is in milliseconds). In my case I just put 0 which is the beginning.
//	loopend is the end point of your loop (same units as loopstart). In my case I calculated the end's time in milliseconds.
//this.bgm = 'url':
//	url is still the url of your music. ONCE AGAIN NOTE THAT THIS IS THE URL OF THE FILE ITSELF.
//If your music doesn't load, you probably put in the wrong site. Try finding the raw audio file (probably can be found through source code of the website).
