Music
I'll listen and dance to pretty much anything, from the Beatles to Baywatch to the Rasmus. The only thing I can't listen to is Rap, Hip-Hop and some harder core dance stuff.
That said I've got a particular soft sport for Hard and '80s rock - Led Zepellin, AC/DC, Europe, Queen and Def Leppard all feature highly on my playlists. I've spent the last 3 years trying to teach myself guitar (without much success because of all my other commitments).
Books
My favourite author at the moment has to be Terry Pratchett. His work is astounding, and I love the way he takes the mundane, and then looks at it at 90 degrees. I'm also a great fan of Trudi Canavan, Carl Sagan and Isaac Asimov.
