Well, what can you expect.. after a few albums, the formula gets old. There are only so many D-A-E riffs you can write before it sounds the same.(especially seeing as AC DC already exploited that formula for the past 40 years). He had a better voice early on but the touring and his singing style has definitely eaten that up. Nothing special in this song. Thought their first two albums had some jam and energy though. I feel for bands and artists over time, very few will consistently put out great material and it must be stressful to know that what you are putting out is not your best. I do give them props for continuing to do what they like though and they have great live energy.
