UPDATE: Harmonix has sent out a press release officially confirming the songs coming to Rock Band as DLC. The first three songs below will contain Pro-Guitar/Pro-Bass charts, and will be FREE from October 26th-November 1st.

According to Paul DeGooyer, Senior VP of Music, Electronic Games, and Programming for MTV Networks:

At the outset of the Rock Band 3 project, we identified The Doors, with their powerful songs driven by intricately woven keyboard, guitar and drum parts, as an ideal partner for our game. As they are also one of the greatest rock bands of all time, we are tremendously proud that they will be the first artist featured in the Rock Band 3 download store and that we’re able to bring this special offer of their music to everyone who buys Rock Band 3 the week it releases.”
