About the theme of Resonant Blue ~
這次的主題是「早安少女組。第2章」
2008年是早安少女組。進入第11年的一年。為了替邁向20週年展翅飛翔的早安少女組。創造出全新感受,淳君在做了許多嘗試後,才完成了這首在早安歷史中不曾有過曲風的單曲。
誠如單曲的標題,本單曲想詮釋的就是「身處都市的孤獨感」。這首歌唱出了女生在都市中的孤獨感,就算週遭有朋友陪伴、生活在喧嚷的都市中心,或許正因為如此才感受到更多的孤獨感也說不定。
My translation (crappy but still ok ^_^ ..... may contain error)
This time the theme is 「Morning Musume. The 2nd Chapter」
2008 is the 11th year of Morning Musume. In order to prepare Morning Musume to advance to 20th Anniversary, after many attempts Tsunku finally completed this single with a brand new feeling which have never seen in previous singles.
Just like the single's title, annotates “the lonely feeling in a city” - Even though the girls are accompany by friends and lives in a clamorous city, yet because of that, may even cause more loneliness.
EDIT: typo, grammar >_<""
