Subject: [PATCH] Listen to Maritime Memory on Wii U Discontinuation Day (#299)

Due to the shutdown of Wii U online services on April 8 at 23:00 UTC
(which affects Splatoon for Wii U), I'm opening a PR to memorialize
Splatoon multiplayer on Wii U by replacing bot music with Maritime
Memory on April 8-9.
