I have like two playlists for my characters. One dedicated for theme songs/battle music, and one for a specific character. I plan to make more but I'm too lazy and most of my other characters I don't have a long list of music that are fitting for.
This is my playlist for theme songs/battle themes (which needs to be updated)
And this is a playlist for my character, Leonora. She's a vampire of the clan Lasombra from Vampire the Masquerade who is pretty much a traitor to her sect/faction, the Sabbat. They don't like traitors, and her clan hates traitors even more than that. So she's pretty much always at risk of being hunted down and tortured/killed by them. She's also haunted by the abuse she suffered by the vampire who turned her, aka her sire.
She's a very strong-willed individual who has a 'if I want it done right, I'll do it myself' mentality. And she is very self-sufficient.
