Sharks are metal heads

It appears that AC/DC's fans include more than just 70s-era rock enthusiasts and Top 40 hit listeners; Matt Weller of Neptune Bay shark cage tours in South Australia has discovered that in lieu of using traditional methods of attracting sharks such as baiting or chumming, he can instead play AC/DC billboard hits such as "Back in Black," and "You Shook Me All Night Long" to attract the sharks.  Weller discovered that when he piped the music underwater, the sharks are attracted to the source of the music and would often change their behavior.  Apparently top 40 hits resonate well with animals whose brain volume is equivalent to a that of a plum; finally, something to explain Ke$ha's album sales.

More research is needed to determine what about those songs and music in general attracts the sharks, however it could potentially be a boon for swimmers and divers- while chumming works to attract sharks for shark dive expeditions, it also is believed to build an association between humans and food for the sharks- not necessarily a behavior we want to encourage.  Apparently thus far, AC/DC is the only Aussie band that the Aussie sharks like.  I suspect Ben Lee's indie pop is too lyrically sophomoric, or at least not head-bang worthy enough.
