Shark Rock

Earlier this week we included AC/DC's 'Thunderstruck' in our list of songs to include in a running playlist, but we may have been leading you astray. It seems that the band's rock 'n roll stylings are more likely to get you chilled out than pumped up. If you're a shark, according to Matt Waller, a South Australian charter operator.

After chatting to divers in Guadalupe who commented that the sharks around them had different reactions to different types of music, Waller experimented with a few tracks and found that the Aussie quartet's ode to amore 'You Shook Me All Night Long' produced a calming and inquisitive effect on the animals.

It's about frequency and vibration more than lyrics, considering sharks don't have ears, and Waller is now on a mission to find something that will repulse the apex predator.

"If there is something that attracts them there is obviously going to be something that they reject - maybe it would be Justin Bieber." His words, not ours.
