Click the housing icon-the one that allows you to place things in your house. Once you're in that mode, click on the music player. I believe once you do that, a little music note icon appears, which you click on to get to the music player "menu." You can add scrolls, remove scrolls, shuffle, and loop music.
Yup. If you have ever had one of the customized signs, it's the same concept. Just click the icon. The first page that pops up is all the scrolls you have in your backpack, and the second is all that you selected to play. Good luck!
