What are some of the most ear grating songs in Project Sekai in your opinion?

I was just thinking about how much I despite Paradichlorobenzene so I googled the worst sounding songs in PJSK. To my surprise, absolutely no one says Paradichlorobenzene even though it’s one of the most nonsensical song I’ve ever heard. I love Len’s voice but he just sounds so goddamn annoying in that song for some reason.
