The joke's actually on me. Someday very soon I'm gonna have to pay for the rights to all these songs. I could get away with it for Book 1 because the only song in it was going to be in the public domain by the time it got to print. But I'm gonna have to pay for these out of pocket. I could always just take the songs out though. This wouldn't be the first time media has been stripped of music because of copyright. It's just the media usually isn't comics. 

I will pay what I owe or the comics will just have to do without. I'm gonna keep adding songs though.
