Angel Beats! OST was one of the best points...
Theme of SSS, Unjust Life, Kanade, Etc... not to mention the OP/ED
Which is why I don't expect the visual novel to take more time to make than Rewrite, as most of the foundation is done, and we also have the OST done.
I just hope they use it of course.

EDIT: I mean, if Jun Maeda doesn't use this I'm taking a plane to japan to personally shove him down a hole
