1. The vocals are definitely better in the demo version, but the arrangement is better in the new version
2. The demo is way better, Hearts2Hearts’ chorus was so so
3. Crazy, this is so great
4. They should’ve released this version instead. The new version is boring
5. Hearts2Hearts’ version is way better. It’s more SM-like and refreshing, and it suits Hearts2Hearts’ voices
6. They’re both good. At first, I thought that SM really became weak with their debut song, but I got so addicted to it
7. The demo was insane
8. The song is way crazier here ㅋㅋ
9. Everything aside, it still sounds like a b-side to me, I don’t know about this for a title
10. It reminds me of f(x)’s 4Walls’ demoㅋㅋㅋㅋㅋㅋ
