I listen to almost every kind of music except rap, hip-hop, and heavy metal. Currently, I mostly listen to Country, Standards, J-Pop, J-Rock, Alternative, and Pop.
A few of my favorites are below:
Nat King Cole - "The Very Thought of You"
Dixie Chicks - "Not Ready to Make Nice"
Kina Grannis - "In Your Arms"
I have no idea why, but this has been my most listened to J-Pop song since watching the anime, Mai Hime.
Aki Misato - "Kimi ga Sora Datta" ("You were my sky") (Mai Hime Ending Song)
