I really love the song. Everyone keeps saying it's so "cheerful" but it's really not. It's a summery-warm, fresh, clean, bittersweet midtempo song. Most of it is in a minor key, too, which you can't really call cheerful. The verse is very distant which definitely fits the nostalgic feel and lyrics of the song. The chorus is sweet, but not perky. I don't think it sounds anything like Replace. Replace was cheerful to a fault, it sounded like cheeseball anime music.

I'm very pleasantly surprised with "fairyland". It's a track I know will be getting a lot of play time from me this summer.

I noticed that too! I was really hoping it would change there, musically. It does sound awkward, but the recording will hopefully sound a little better.

I'm translating the lyrics right now (Just need to finish downloading the video so I can check the subs and make sure my ears aren't decieving me). If the song has any fault, it might be the lyrics. They're not bad at all, just seem kind of average to me. She mentions "ano ko ya aitsu" again... That's 3 songs, isn't it? (immature & Heartplace, & now fairyland) I wonder who those two people are. She always refers to them when she sings about her youth and innocence.
