|This is an April Fools' Day version of Music Extension. Please don't take it seriously. You can find the original here.|
The Music Extension is where people put their custom music in and it automatically makes it better or worse, depending on how much energy the Scratch Team has gotten from them. Even if you have the best music in the world, it still can make it better. You never have the best music. You never will.
Of course, it works vice versa, but if you have the worst music, it just turns it into an hour long noise of "you have the worst music you nub".
Sometimes, if the Scratch Team has taken away exactly 666 energy points from you, it turns into a Rickroll.
Not many people have tried this out, but those who have find it very useful for making things like songs to impress people. The code to do this is sadly outdated, so you have to travel back in time to somewhere around 4000 BC to make it. The code for making a time machine can be found here.
