To all of those dealing with those Muzak blues, I might just have the cure for you

Ok what you need to do is turn the muzak palyer around so that you can see the back of it. Now looking at the back you will see on the right hand side a switch pannel its very small. You will notice that they are all numbered and that #'s 1 and 2 should be flipped up, what you want to do is flip #4 up and volla, You can now play normal cd's in your muzak player. This little feature saved many employee's at my company I hope it can do the same for you.
