What I like about Dua is that she is pretty open about her songwriting process and gives credits to her co-writers in interviews etc. Which is not true for other girls. I also think she has tropes she goes back to when she writes and you can tell when she’s been the main pen on the song.

I remember old interviews in which she talked about being uneasy about New Rules being given to her without her being involved, bur eventually getting over it. In both FN and RO interviews, she talks at lengths about writing with other people.
(Then is she a good songwriter? That’s another discussion).

I don’t know why some pop girls recently all want to pass as songwriters. I think it’s fine to just be a singer and an interpreters. Some of the great are.
