World of Warcraft music for sure. I listen to it when I'm basically doing anything whether it be RPing, writing my book, doing homework, even at work sometimes. Nothing beats it for me, I just love the theatrical fantasy sound.
I miss LiveJournal so much!! That place was a haven for weebs like me back in the day.
Warrior Cats RPG (which became FeralFront) was my jam for a long time, but before the change in leadership. I loved that place and I'm sad it's no more. I hope to find my place on this site now!
