I'd highly recommend browsing a Miku thread or two (current one here:
>>1544344 though it's getting kinda old), as she's gonna have a lot of what you're looking for (musical female solo).
I'd also suggest throwing a few Powerlevel ones (real ones) that you recognize, simply for the occasional "Aha!" that you might get.
Anyways, my best contribution, wasn't already in the Miku thread, but since you found me first, you get her instead.
