how to set self.getSoundByURL(soundURL) unique key?

[thadeu]

Problem

In my case, I have many sounds with same URL, but I would like that it was different player instance.

Today self.getSoundByURL(soundURL) get search into self.soundsByURL[soundURL] based soundURL, how to make that soundURL be unique and not side effect others player on the page?

Example:

var url = new URL(o.href)
soundURL = o.href + (url.search.length ? `&overcache=${Date.now()}` : `?overcache=${Date.now()}`)

But, when to createSound use it:

thisSound = sm.createSound({
       id: 'ui360Sound' + (self.soundCount++),
       url: removeParameter(soundURL, 'overcache'),
       ......
})
