Discovering Bach

So I have come to like many of Bach's works now that I have begun to listen to some of them. I had a great discussion on the tabletalk chat about which one's I should listen too since I am just starting out. I happened to stumble upon the Itunes Essentials in the music store which coincidentally released a list of many of Bach's works. If you don't know where to start and you are an Itunes user I suggest you check it out. Oh and if anyone wants to recommend some personal favorites for me to listen to feel free.
