_ 世界が望んだ忘れもの
ZONE が歌ってたアレは当時は「友人たちとの夏の思い出は最高なのよとても素敵な思い出になるのよ感動なのよ大人になってから思い出すときっと泣けるよひととして良い思い出になるのよ」という歌詞と曲の感動の押しつけが鼻について隣人部の私にそのようなドラマチックな( ドラマ風な! )展開があるわけねーだろ常識的に考えてようするに非常に欝陶しいし嫌いだったんだが、あの花を見てから印象がまったく変わった。この歌は素敵だ。あの花のためにある歌だ。歌を聴いているだけでまた泣けてくる。( 相変わらず自分の経験に基づいた感動ではないあたりが隣人部クオリティ! )
ところで編曲は @btc_toku だったのか今更気付いてごめんなさい。
