I choose to think of it as the pre-chorus now typically the pre-chorus comes after the verse and before the chorus here there is no chorus that follows it it just goes straight into verse two but that's not totally unheard of in pop music and rock and things like that and the next time the pre-chorus happens it does lead into the chorus so I justify that
pre-chorus 前副歌
通常銜接副歌,但此處第一次出現後,又立即回到主歌。這在流行曲和搖滾樂並不少見。
