Last night on iTunes I downloaded Beethoven: The Complete Symphony Collection by the London Symphony Orchestra & Josef Krips. It's awesome! It has Symphonies 1-9 and is about 5 1/2 hours of music. The best part is that it was only $9.99. Talk about a steal! Check it out if you're ever in the mood for that sort of thing.
My music tastes are pretty diverse. I really like just about all types of music. I tend to go through phases where I listen to one genre more than the others. Recently I've been craving classical music. I'm finding it to be very good brain food while I'm working. For whatever reason, it doesn't distract me and I believe actually increases my creative energy. The problem is I don't have a ton of classical music to choose from.
