I would keep it as Book. The songs might have come first, and they might be more in number, but they definitely feel second to the books. It might not mean much considering the bulk of the English speaking fandom that comprises this wiki can't access the books or read decent translations of them whereas the songs are easy to access both in listening and translations, but those novels ARE the story. The songs are add-ons to give a sense of theme and atmosphere. Everything we're supposed to know about the characters, their actions, and their backstories, are in the novels. Compare to other song series that don't have novels, where lyrics or PVs provide explicit exposition on who the people in it are.
