Great album. Stand out songs of course are Hells Bells, Back in Black, and You Shook Me All Night Long. Other than that, I wouldn't say there were any hidden gems here. It's all quite standard hard rock. None of it bad but I think they should have spaced out the latter two a little because the last 3 songs feel like an anticlimax after two legendary songs in a row. It's not quite a 5, but it's close.
