Anyone know any VN's like this anime?

[torbin12]

So, I was wondering if anyone knew any VN's like Shinkyoku Soukai Polyphonica Crimson S in the aspect that music is used in a somewhat un-orthodox (read here as 'normal', not as part of a religion). Like, they use them as Commandia's, not necessarily just as a band.

The setting can be different, the theme can be different, it's just that aspect I am thinking of. Male protagonist would be preferred, as would one with some romance.

Thanks for any help you guys can offer.

Shinkyoku Sōkai Polyphonica ?

Symphonic Rain and Rin ga Utau maybe?

Ar Tonelico series are probably the closest one I can think of, but that's not pure VN
