. (M. Sean McClintock, Neon Sagwagon) "Jealousy" was written by
Heather Baron-Gracie (lead singer and guitarist for
Pale Waves) and Whakaio Taahi (a singer-songwriter who had previously been the lead guitarist in the band
Tonight Alive). In terms of genre, "Jealousy" has been described both as a
pop-punk and an
alternative rock track; In a description of the track's soundscape,
Alternative Press wrote that "each verse of 'Jealousy' is akin to a blade grinding against a
whetstone. The vocals are just barely covered by the gritty tones of their accompaniment. When the chorus comes around, [Baron-Gracie's] voice has obtained a razor's edge, and every other sonic element is cleft by her enthusiastic delivery." The lyrics to "Jealousy" which are sung from the perspective of a possessive lover who is cognizant of her behavior were inspired by Baron-Gracie's personal feelings about the titular emotion: "I love a bit of jealousy not too much, but just enough." When speaking with Amfo, Baron-Gracie expanded on these sentiments: "I just embrace my craziness and sometimes you just have to let it loose, and 'Jealousy' was that for me. ... Yeah, I ... think the right amount of jealousy is healthy. Like, I would want my person to get jealous. I wouldn't want them to just be like, so cool all the time. I'd be like, 'No, you need to be jealous about this,' you know?" ==Music video==
