Okay hear me out Junkrat's theme song is totally "What a Fucking Lovely Day" by Stephin Merritt. He sings it while blowing shit up and you know it.
holy shit this is so his style wtf the fuck,, the lyrics and the style of this song and everything is so HIM. i can easily picture ‘rat screeching this on a day to day basis, 24/7, and roadhog wanting to rip his ears off after the very first hour of it. ((junkrat sings it so much that roadhog unintentionally winds up learning the lyrics by heart and at times, even absentmindedly humming it himself, much to his chagrin
