Usually I don't give them actual theme songs, but I always manage to find some songs with lyrics corresponding with their personalities or their attitude towards specific situations. That being said, I think that "Blood" by Dropkick Murphys fits my Hawke quite well
I LOVE that so many have entire playlists <3 (i'm not alone!!! lol) i too have a massive playlist, but my Warden's "theme song" is I Am the Fire by Halestorm. I keep a playlist of the songs I use for my fic though, if anyone's interested (I know music is incredibly inspiring) (not the order they're in the playlist unfortunately).
Well, I have some that I do and some that I don't. The ones that I have though: My baby Robert Hawke's is "Gold" By Imagine Dragons (it was almost another one of their songs "Bleed It Out" but Gold barely won out). Tobias Hawke's is "Wake Me Up" by Avicii (but I like the cover by Boyce Avenue better than the original). Eric Cadash' is another Avicii song "Pure Grinding" (don't ask) Both Tamriel Lavellan and Talan Adaar are extremely hard to pin down so they have a whole slew of songs. Jarod Aeducan's had always been "Headstrong" by Trapt I have a whole bevy of other DA characters and all of them have songs that could be their theme songs but like Tam & Talan, they're all over the place.
I don't really have songs for particular characters but I do have a playlist that I refer to for any Solavellan work I do. I really like "Falling Slowly" by Glen Hansard and Marketa Irglova and "Lie to Me" by Sara Bareilles are good for the relationship.
Also, ever since I first heard "I Dare You," by Shinedown "many" years ago (lol) I thought it was perfect for Anders.
I just think of 'Discord' sung by The Living Tombstone for my Inquisitor Lavellan. Mainly for the lyrics "Are we just a stepping stone for taking back the throne" and "Whatever did we do, to make you take our world away".
Roby Fayer - Ready to Fight is perfect for my Taerel Lavellan and his wobbly relationship with Solas. He doesn't disband the Inquisition and he feels utterly betrayed by what Solas did, and Taerel told him that he will stop him at all costs. He will fight. And still, there's a part of him that he can't ignore that wishes that he could have back what he and Solas had. That Solas would just listen to him and stop this mad quest of his and come home. Taerel knows better but deep down he's fighting for that too.
I 'dedicate' an entire album to multiple of my DA OC's, Slash's World on Fire. To note a specific song on it- 30 Years to Life, referring to jail time, but also fits very well for Warden characters given their 30 year lifespans. I'd definitely like to do a set of artworks to each song when I get the time.
