Manic Songwriting Credits by Halsey

Manic functions as Halsey's most autobiographical record, with the singer credited as a writer across the album and the opening track Ashley using her birth name to frame the project as a self-portrait. The album threads in three guest interludes that act as outside voices commenting on her arc: Dominic Fike on Dominic's Interlude, Alanis Morissette on Alanis' Interlude, and Suga of BTS on Suga's Interlude, each contributing their own writing and performance rather than appearing as a conventional duet partner. Halsey worked with a wide production roster including Benny Blanco, Greg Kurstin, Louis Bell, and Finneas, yet kept her lyric voice central across the genre shifts from electropop to country and hip hop. The result is a co-written but author-driven album where the guest spots deliberately interrupt Halsey's narrative instead of softening it.
