For music, my favorite genres have to be Post-Hardcore (Sleeping With Sirens, Pierce the Veil, and Alesana to name my favorites), and K-Pop (2NE1, 2PM, and Wonder Girls).
Books: anything written by Brian Sanderson is immediately my favorite piece of literature. Mistborn, and the Way of Kings are just phenomenal. A close second would have to be Jim Butcher, and his series the Dresden Files.
Good fantasy literature
