yesss dude yesssss... I've had a personal playlist for literal years but that stays between me. So i'll just list some songs instead. I feel like people often mix up songs that remind someone of xyz character vs songs that xyz character would realistically LISTEN to. So i'll give my answer to both, kinda.

For songs that remind ME of them by (mostly) lyrics and some vibes,

IFHY/HER- Tyler the Creator
The Masochism Tango- Tom Lehrer
Love Me Dead- Ludo
Join Me In Death- HIM
Paralyzer- Finger Eleven
You're A Cad- the bird and the bee
Hospital Bed Crawl- The Hush Sound
Rule #7 -Angel Tango- Fish in a Birdcage
Dirty Business- The Dresden Dolls
Stuck With You- Aurelio Voltaire & Amanda Palmer
Talk to You- Ricky Montgomery
Dearest (I'm so Sorry)- Picture Me Broken
La Circula- Nico Play
Clusterhug- IDKHBTFM
Dirty little Secret- The All-American Rejects
Never Love An Anchor- The Crane Wives

Whilst for Ben and Jinx themselves, I can't list any songs I think they'd listen to (since going through the process of finding specific artists is a hefty feat and I don't have that level of passion for music) But I can say the genres they like. Jinx likes nu-metal, alt-rock, and hiphop with a keen interest in shock value bands. However he'd be a pretentious ass who only likes underground musicians and opposes anything in any circle of popularity or recognition, but he's also generally more interested in local singers. Ben's music taste consists of classical, lofi, and anything that's on the radio. He likes something he can play in the background and relax with, he finds it calming. I can't imagine him being a major fan of any bands or really big on songs with lyrics.
