How can someone hate Play Ball?
I'm biased because I don't actually hate any of her songs, but my least favorites are definitely Flavor Of Life, Kiss & Cry, and Poppin'
Also as an unpopular opinion, I'm not in love with Beautiful World at all. The melody is really nice, but I just hate her voice in it. It's when she was losing it and you can definitely tell.
I also don't hate Boku wa Kuma because, for what it's intended to be, it's really well done. It's a children's song, and that was always what it was supposed to be. I don't believe it belonged on HS, but that's a different story lol.
