I've been listening to Lord of the Rings on audiobook. I rewatch the movies and reread the books every year or so.
The Hobbit reminded me to do it again. Being a college student I decided to do the audiobook for the first time and I have to say, it's fantastic. I've been using Audible. I think it's $15 every month and you get 1 credit which can go to any book regardless of price, which is cool because the LoTR audiobooks are $26 a piece!
I'm going to reread the Silmarillion as well.
But I have a long list of books I need to read. I'm currently trying to catch up with the author of the Drizzt Do'Urden series. He keeps writing them and I can't keep up! If anyone here likes fantasy that's an amazing series.
I'm also trying to get through some educational/nutritional type books. Sugar Shock and The End of Overeating are the two I'm most focused on.
There's a cool website called Books Should be Free where you can listen to audiobooks free and with no download, in various languages. I believe they are books from the public domain read by volunteers, so some of the quality isn't the best, but some are pretty good.
