If you're wondering about some of the curiously titled songs, "Mononofu" translates to "samurai". I'm not sure what "Ayakashi" means though. Google just goes to "Omakase" so I'm without a paddle there.
"Ayakashi" is an older way to call Yokai/Japanese monsters. "Omakase", literally means "up to you", is the whatever the person who offers the service decides what to provide instead of customers deciding for themselves.
