OK, so more questions...
1] I notice that when I go to "Edit Customizations" the 'Free Text' area disables all HTML. Is there a layer that can get around this?
2] I tried adding a second Music/Book component. I just copied the first one I did directly and then changed the appropriate areas; however, it doesn't show up. Apparently, you can't just add a second one that's identical. When I went back to read through the tutorials, I was confused as to if I should be reading the "Mixed Components" or something else. Even so, when I did read that tutorial it just lost me more *sigh*
3] How do you add this second, italized line to the Music component like here

I think that's it for now.
