One of my most favourite songs of all time. I regularly gooi it at ear bleeding levels.
There's no accounting for taste, is there?

Seriously, you are not alone in your enjoyment of that song. I was talking as someone who grew up with AC/DC and who owns all their early albums. I suppose one gets used to a particular sound from a band and then loses interest when the band departs from that formula. Another example is my enjoyment of Bob Dylan's early albums and the corresponding dislike of his later albums. Likewise, I enjoy most of Iron Maiden's albums with Bruce Dickenson on vocals, but my favourites are the first two albums with Paul Di'Anno on vocals.
