Really torn on this. The only song I don't actually know if Blackout by Scorpions, so it's the weak link in group 1. But Smoke on the Water, Eighteen, Shot in the Dark, Unchained are all songs I can't stand, and each of them have 2 other awesome songs to balance things out. Think I have to go with 3 by virtue of Dio and GnR picking up Cooper's slack but the rest are very close.
