Anyway it nothing except
uneducated to claim repetition of lines is always due to being "rushed" or somehow merits "weak" lyrics.
If you have studied poetry at any depth you would realise repetition is sometimes essential and often artistic.
In 'We Found Love' the line was used as like a mantra. It was obviously the focus of the song, like a repetition to represent the euphoria of the moment. It was like illusions and delusions of delight being expressed. The lyrics are some of my favourite ever actually despite being sparse.

You gurls are trying too hard tonight.
is this a hint?
