Dalish warrior vs Solas - a change from all the classic rock to be a bit more cerebral with Sparks, When I'm With You (I lose a lot of sleep when I'm with you, lol)
I'm damned if I can think of anything for Blackwall and don't know enough about Josie to pick anything. It'll be interesting to come back and see how appropriate these choices are once I've played the game...
This was really fun, thanks OP!
EDIT: FFFFFFFFFFFFFFFFFFFFFFFFFFFF WHY ARE ONLY SOME OF THESE WORKING THE CODE SEEMS FINE
Divinyls are an excellent choice for all female characters - I could also have gone with Siren for Sera!
EDIT: In principle I mean, ignore the heterosexuality. The weird thing is I actually rejected a different Suzi Quatro song for her because it was obviously about a man. DUH.
