The White Dark Life roleplays frequently link to music, and much of it is awesome.
- Cassandra's theme song is "Rush" by Aly & AJ, used to represent her personality as a nigh-fearless Determinator who lives her life to the fullest.
- Lindsay Dawn's theme is "Someday (August 29, 1968)" by Chicago, interpreted here as a Bully Hunter anthem emphasizing the inevitability of the wickedness of bullies coming back to ruin them (with Lindsay herself as an embodiment and deliverer of said inevitable and well-deserved ruin).
- Saliva's take on the Spy Hunter theme originally served specifically as a theme for Bowser Jr.'s burning desire to kill Lindsay Dawn in vengeance for all the havoc she's wreaked on his father, Bowser (especially the "bomb up Corneria's butt" incident). It has since become a Bootstrapped Leitmotif for Bowser Jr. himself (but still usually used in the context of him trying to kill either Lindsay or her daughter, Leila).
- Mysto has quite a few theme songs to her name:
- Her primary theme is "With Me" by ALL ENDS, originally Merlina's boss theme in Sonic and the Black Knight. Mysto knows she's evil, but fervently believes that she's working towards a good cause...
- ...that cause being the restoration of her people's old way of life and the obliteration of those who originally destroyed it, as shown in her secondary themes, "Words of the Witch" and "Pagan Glory" by Lonewolf.
- Her fourth theme is "Cadence of Her Last Breath" by Nightwish, but this is more frequently used for her subordinates and minions. It originally represented the Dastardly Pack running Annie down, but has since branched out to represent Mysto's desire to destroy her enemies, and how she'll use everything at her disposal to do so.
- Mysta's theme song is "History of the Moon", originally Eirin's theme from Touhou 6: Imperishable Night. He also uses the song's various remixes when he gets serious — except for his Last Word, which uses "Just Three Days" by MandoPony instead.
- Drathilox's theme is "One Vision" by Queen, reflecting his desire to unify everything in order to put an end to violence (according to Author!Luigifan, Drathilox is basically an (accidental) expy of the Borg).
- Lydia's theme is "The Shining Polaris", chosen for being an energetic song with a strong light motif and an undercurrent of seeking romance (referencing Lydia's love of Disney-style romance, which she found for herself with Prince Sunlight).
- Icing the Rabbit's theme is "Engage the Enemy" from Xenoblade Chronicles. The song was selected to reflect the pain and anger that drives Icing to exterminate Seedrian-Mobian hybrids in his bid to undermine the Trophic Blenders. note
- Moge-ko still has her signature "Karugamo March - Sinken" as her main theme, but both she and King mogeko also get Neku's remix of the Mogeko Castle title theme as their boss music. (King mogeko's fight in "Scaredy Fox Training" retroactively gets the song applied to it, while Moge-ko doesn't use the song until her return as the primary antagonist of "Scaredy Fox Training 2".)
- One Night at Flumpty's: Flumpty Bumpty's leitmotif is "Flumpty's Jam" by DAGames — a jaunty tune for a fun-loving egg.
- Viv Prower, the electronic poltergeist, has The Living Tombstone's "Die in a Fire" as her theme song. While the song was originally about the Purple Guy trying to erase the evidence of his crimes, Viv's interpretation focuses on her murderous hatred of Miriam Calibur — and the song still works just as well, especially during her debut in "Scaredy Fox Training"note and her tenure as the main antagonist of "Important Character Update"note .
- Despair!Matt gets good milage out of stealing Monsoon's theme song The Stains of Time. The meaning might be more literal in this case, as Matt's completely given up on everything beyond the contract he has as a Guardian Angel.
- Luther and Lindsay's romance theme is "You're My Best Friend" by Queen, emphasizing their strong lifelong friendship in addition to being lovers.
- Lydia and Sunlight's theme is "(When You're Ready) Come and Get It" by Selena Gomez, symbolizing both the strength of their bond right from the start and their desire to not ruin it by getting too passionate too quickly.
- The Slavic Circle has taken up "Left Behind" by DA Games as an anthem, representing their desire to destroy the Abrahamic religions as a preemptive strike to protect the resurgence of their own religion (which had been stamped out by Christianity in its earlier days, back before "religious tolerance" was recognized as a worthwhile ideal). (Snake-Jaw in particular uses the song as his personal theme, symbolizing his desire to reclaim Maxmillian as his body, using the "Nightmare Edit" when it becomes Ennard in a gambit to take Synder's skin and use it to ambush Esther.)
- The Happy Sperm Club has two themes — "Pain Redefined" by Disturbed and "Wish I Had An Angel" by Nightwish. The former song emphasizes the mess they make of their victims' lives (including Lillian), while the latter song emphasizes their horrific treatment of their captives (as Author!Luigifan says, the refrain of "Wish I Had an Angel" can easily be taken to sound like the narrator is about to kidnap a woman and rape her repeatedly).
