9/2 EDIT: I linked to what seems to be a different version that plays mp3 versions of the music. the old link is still below. I also made some changes in the music changing thing. I've tested it in IE, Firefox and Seamonkey and it's a yesgo.

Chromium-based (chrome, opera 13+, chromium) don't seem to work, and neither does old opera for this "nu" version.

So yeah, it looks like ie-based and firefox-based the music works, and loops.. and can be stopped. There's no normalization/eq and though it's not horrible, some tracks appear louder than others. That's just how the encoding works.

It almost seems like both entities exist, old midis and digital tracks, I can't verify though.

Made also a placeholder multiple choice for a new chapter.
