The strategy you can bring to AC/DC is second to none. I doubt there is any one true way to play the game, as it very much depends on the situation you're in
For example, if you're launching your last ball and have the chance to change songs AND have a few VIP passes in the bank, it may make sense to start Hells Bells. That way you can use your VIP passes to more easily ramp up the score multiplier
Or if you're ready for starting Album multiball, and have the chance to change song, switching to TNT makes sense, as you can build up your song jackpot whilst making multiball jackpots
etc etc
Phenomenal game. There is a ruleset posted online, but it doesn't really discuss the depth of strategy, just explains how points are awarded : http://pinballarcadefans.com/showthread.php/4761-For-Those-About-to-Rock-AC-DC-Premium-LE-v1-65-Ruleset
