@tea69boss I do not know if you would like to use this but I have added the ability for your loadingscreen to play multiple songs while loading in. Granted there may be flaws in it but it will allow you to change songs and add as many songs as you may need. I highly think you should use this for your script. I give you full permission to use as you please. All I want to do is help my fellow players out is all. I also encourage anyone if they think they could improve on it to do so. All I ask is if you do to post it here and to give tea69boss credit for it because afterall he did create the initial custom loading screen!

Only issue is that we need a cursor active on the screen for you to click to switch between songs and I am not sure how to add that. If someone could figure that out that would be great! I found this link but not sure how to impliment: Cursor on loading screen
