This is probably the worst question for me to answer, my tastes are
so wide and open that it is hard for me to narrow them down
I read everything from news articles to fantasy and fiction.
Historical literature and crazy new modern fiction.
Same applies to music, being a former music major I have listened
to, and performed a wide variety. Classical, orchestral, choir,
jazz, rock, heavy metal, blues, etc etc.
Some of my favorites, to just name a few that come to mind
Books: Clive Cussler: Dirk Pitt series, Harry Potter (since they
came out while I was middle school, don't judge me), The Alchemist,
The Road Less Traveled.
TV: House, Glee, Big Bang Theory, Who's Line is it Anyway,
Music: Rush, Muse, Breaking Benjamin, Iron Maiden, Frank Tichelli,
Transsiberian Orchestra, Supertramp.... the list goes on.
