I was looking around Gamestop’s website when I happened to find the full list of songs and the first ten songs that will be on the DLC. I have typed below all details about Rock Band Unplugged

Rock Band Unplugged combines traditional beat match gameplay with elements from both Rock Band and Rock Band 2, delivering the Rock Band experience to the player on the go. Rock Band Unplugged will build on the plate-spinning gameplay model of previous successful beat match games as well as incorporate many key gameplay elements of Rock Band 2, such as overdrive and chords. The look and feel of the Rock Band brand will be apparent throughout the game. All this will be accompanied by a rich gameplay experience built on the Tour model established in Rock Band 2. The player will travel the globe, play gigs, acquire fans, and rise to the top, becoming the greatest band in the world, all while riding the train to work.

Features

• Take the Rock Band experience on the go! Unplugged will give players the addicting full band experience where the classic beat-matching music gameplay has an innovative platespinning twist – you need to keep all instruments going at once!
• Extra Gameplay Modes: Unplugged includes not only the classic Rock Band World Tour Mode, but also Band Survival and Warm Up Modes that give players even more gameplay options.
