A way to do stuff when an interactive audio stream switches clips

[Seboops]

You can tell an interactive audio stream to switch clips, and sometimes it doesn't switch immediately. This is good, this is what it's for. However, because of the delay, it can be hard to make stuff happen when the music actually switches. So maybe some kind of signal, or any way to call a function when the clip switches would be really convenient. For example, in my project, I want to play an animation once the music switches for dramatic effect. I want to make the music switch on the bars. I don't want to have to do a something like checking the last frame's clip and comparing it with the current one to see if there are differences.
