I am so very terrible with songs and I can't get links at work, but. Thanks to Fry "Hiw Strong Do You Think I Am" by Alexz Johnson has always been my younger Jaina anthem, while Guster's "Lightning Rod" is her as an adult, and "After All" by Dar Williams is very much her post-LOFT song.

And "Empress" by Snow Patrol is the song that very much screams post-TLJ Rey to me.
