Iced Earth's Songwriting

I gave Iced Earth songs the same analysis I gave Dream Theater songs: who wrote how much of each album. Iced Earth's results, as expected, look quite different than Dream Theater's:

Horror Show happens to be my favorite Iced Earth album. Clearly I prefer Barlow's lyric writing and Jon's music writing. Burnt Offerings has the least music that Schaffer wrote, which may explain why that's his least favorite Iced Earth album.

Anyway, I'll stop nerding over songwriting credits... for now.

Note: I was going to do the same for Opeth but the vast majority of their music is credited to "Opeth" and most if not all of their lyrics were written by Åkerfeldt.
