did remove on 00:48:164 because the piano is contrast here, keep other.
00:50:209 - bass -> violin blends
01:05:618 - violin -> string blends
01:07:664 - bass -> violin
`applause.wav` is there to ranking screen, so the music at the end doesn't get covered.
it's a 44 KB wave that usually used to mute hitsound, should be fine to use here.
follow melody, and 00:06:913 supposed to be denser.
applied following changes instead:
00:06:640 - moved to 00:06:504
00:07:322 - add note
00:09:504 - add note
i mapped those before, but it makes this section feels like have same contrast with 00:37:458. leaving this gap would make it feel calmer compared to next section.
