I watch tons of TV, but my favorite shows are Gossip Girl, Friday Night Lights, Lost, Glee, Dexter, True Blood, American Idol, Dawson's Creek, Heroes, Veronica Mars, Alias, Buffy, So You Think You Can Dance, and How I Met Your Mother.
My favorite authors are J.K. Rowling, Madeleine L'Engle, Megan McCafferty, Tamora Pierce, Sarah Dessen, and Meg Cabot but I'll read basically anything.
As for music, I listen to basically anything but jazz and rap, but I especially like David Cook, Keith Urban, Kelly Clarkson, Adam Pascal, Taylor Swift, Miley Cyrus, Carrie Underwood, Adam Lambert, and many other former American Idol contestants. I actually listen mostly to cast recordings though, especially Next to Normal, Spring Awakening, In The Heights, RENT, Wicked, and Aida.
Other than LJ, I spend lots of my time over at Television Without Pity (my username is Freckles101).
