TBQH though, it isn't the best choice from them. Battle of Evermore is essentially just vocals and mandolin (can't remember if there is guitar or not). I am not sure how I feel about Stairway to Heaven in this game.
Black Dog would be fun
Rock and Roll would be epic epic win
Battle of Evermore... see above
Stairway to Heaven... Guitar is epic, vocals is awesome, drums and bass leave some to be desired me thinks (though I guess they are there for the last half of the 8 minute song)
Misty Mountain Hop would be fun
Four Sticks would be decent
Going to California is another track with vocals and guitar/mandolin only
When the Levee Breaks would be epic win. It is repetitive, but I would be jamming too much to care.
