Eee! This is among my favorite things to do!
I regularly listen to Queen songs and think about Jokers, especially We Will Rock You, Don't Stop Me Now, and Crazy Little Thing Called Love (Killer Queen is a Libby song though). The
lyrics of Head Full of Doubt/Road Full of Promise by The Avett Brothers make me think of Jokers, but musically, it's a bit twee and folky for me to feel comfortable labeling it a Joker song.
The song Dreams by The Twilight Hours reminds me of Aether, but I have yet to find a song that accurately represents Essence of Bell. I'm having this same problem with Adarins. More research is necessary!
Most songs by the Dixie Chicks are Zev songs, particularly Cowboy Take Me Away (works better if you imagine the cowboy represents courage or perseverance or stubbornness or something) and Not Ready To Make Nice.
(Annd my embedded links are refusing to work today! Here's the one for Dreams because it was hard to find, the rest are easily google-able!
