I've always found "Crystallize" to be one of the most disappointing tracks in Kylie's discography. It's fine, I guess—but considering the talent involved, fine isn't good enough. I remember when I first discovered that they were going to release a Kylie × Dev Hynes track and being so excited, especially because this was after "Everything Is Embarrassing" and "Losing You"—two of the greatest songs of all time—and then being just whelmed when it was actually released. "Crystallize" is yet another "I Believe In You" redux—it's cute, but hardly essential, which makes it the perfect charity single. I gave it a six, which is actually quite surprising because I would've thought that I'd give it a sub-five score.
