By music maker, I assume you're talking about the "box" that says "CD Player", correct? For future reference, that's just, as the name says, used for listening to CDs, should you feel like listening to one on your PlayStation. But, I digress, the screen as a whole pops up when the console's lid is open, when the console thinks a disc isn't placed in it, or when it detects a CD. Are you sure the lid is closed completely? My Playstation's lid stays popped up a bit, even when it clicks closed; I have to put something like a book on top of it to weigh it down so that it's fully shut. Perhaps your discs are a bit dirty and/or scratched instead and they can't be properly read? Otherwise, like it already says on this page, maybe your spindle hub is damaged, or it could be something wrong with the console's laser; either issue can cause a PlayStation to be unable to read the disc correctly, resulting in that screen showing up whenever you use the system.
