Wow Lisa...I had no idea! Mad respect for you.
My list of music that takes me to my happy place isn't really in line with my age. Though I tend to be all over the place and depending on the season depends on the genre of music I listen to.
My happy place tends to be melancholy. My typical go to artists are The Arcade Fire and The National.
I am also in and out of contemporary folk, Blue grass, New Grass and the such. I listen a lot to The Avett Brothers, Old Crow Medicine Show, Trampled by Turtles, and Kasey Chambers.
Sometimes I will listen to older Guster albums and older Death Cab for Cutie. I really enjoy listening to The Postal service from that time as well.
Some of the newer artists I will occasionally listen to are Chvrches, Imagine Dragons, The Head and the Heart, and some others.
Of course if I want to go back to my musical Gen X roots and be angry again...I will listen to Depeche Mode, The Smiths, The Cure, and some others.
Some others I will just randomly through in there that I listen to are...Lord Huron, The Decemberists, Strumbellas, Modest Mouse, Father John Misty, AWOLNATION, Bon Iver, Cold War Kids, etc.
My absolute get in a relaxing mood album is...Lost in the Dream by The War on Drugs!
