If the lyrics were all generated by a Markov chain from beginning to end, there's no way that it would have a repeating chorus. Are all the 3-word tuples actually used in other AC/DC songs? (Output this grammatical could not be generated by a Markov chain that only looks at 2-word tuples.) If not, that also seriously calls their claim into question. I think the maker would have done well to be more upfront: "AC/DC Song Co-authored by a Computer" or something like that.
