Okay, let me give an update on the situation here.
I think I'll have the art side of things for the first Chapter of the Touhou Mecha VN ready sometime mid-March. It's probably not a good time of year to find musicians with spare time, so I've actually decided to use some CC (Creative Commons) music from jamendo.com, at least for the first Chapter release. We'll see if we're able to replace it after that.
I'm hoping this'll accomplish two things: First, people will see that this project is indeed getting done and that it's worth working on. Second, people get the chance to see the context in which the music is used and and general ballpark on the desired genre from what I pick out as placeholders.
CC music isn't low-quality stuff by any means-- rather the opposite. This means the standards for the soundtrack are going to be higher now; it's going to be a balance between getting a good soundtrack, and getting something we can call our own. Other than coming close to the quality of the CC tracks, factors that'll help to get in are:
1. Landing in the genre range. Currently the more emotional pieces use synth orchestra with some rock instruments thrown in. FlameZero's piece is going to be in there, and pretty much the sole hard rock representative so far. (There's one battle scene so far, so there's room for more...) There's a darker mission-sounding track with a slow pulsing bass in there, and for normal conversation there's... soft rock? Lounge even? Don't know how to classify some of them.
2. Touhou Project arranges like in ESR.
3. Something like a "main theme" for the game, like a recurring melody if you decide to compose several tracks (or even the whole thing!)
To Anunsew, I offer my apologies. The two tracks you offered in the first round are pretty much what I asked for, but they didn't amaze me so in the end I decided not to use them. If I knew how to put together music decently well, I'd do it myself. Unavoidably, there's going to be an element of "I'll know it when I hear it" at work here, which also comes from the fact that there's a lot of variation in the kind of music this community makes.
At any rate, for now it's just something to consider for the future. Thanks to the people who offered music samples last year. Please look forward to this game's initial release in a few weeks.
