Homework- I suck at listening to music and focusing on homework, although tv really helps if it's in the background while I'm working. Weird eh...
Relaxing- Coldplay! But not all of their songs, mostly the slower ones like Lovers in Japan, See You Soon, Trouble, etc. And Goodnight Boy by Arcade Fire, I LOVE that song so much. And MGMT <3
Chilling- POKEMON MUSIC! And Glee. Stuff to sing along to.
I like to pretend I'm at my own giant birthday party filled with everyone I love and/or want to meet, performing on stage doing Pokemon or Harry Potter skits, or singing along with the Glee cast etc. Best day dream ever! (especially because there's always a giant pile of presents....nom)
