I personally would switch #1 and #2 but I'm still glad they're your top 2. They really went off with that first single, blessing us with Sing & Smile!! and Beautiful Moonlight. That instantly made them my fave Niji subunit, even though I had the least expectations for them prior to any of the subunit singles being released.
Last place is my #2 and my #1 is your #2. Kinda can’t believe Makeup Session ABC is so low…but I get it. It’s really hard to rank the songs of the one LL subunit that’s never had a bad song (imho at least)
Apart from four seasons I honestly didn't really know where to put everything but since I haven't really listened to make up session ABC that much (it isn't on spotify), I just put it the lowest of the other ones. But I don't have a really strong favourite for QU4RTZ
For me Not Sad is #1 Qu4rtz song 1. Not Sad 2. Twinkle Town 3. Sing and Smile 4. Swinging 5. Make-up ABC 6. 4 seasons 7. Beautiful moonlight 8. Fuwa fuwa hour 9. Michi no saki 10. Enjoy it 11. Pastel (this is the first time I'm still not impressed by a Qu4rtz song even after listening it for many times)
