It's time once again to face the unruly challenge of having to pick between your favourite (musical) children but it's here: the triple j Hottest 100 voting has now opened. 

To celebrate, triple j have enlisted their resident scientist Dr Karl for a mini-documentary exploring 2016's favourite musos in their natural habitats - catch Bec Sandridge, Tkay Maidza, Peking Duk raving in the Dankest Place On Earth, Client Liaison "cutting sick on the D-floor", Montaigne struggling through the wilderness, drinks in hand — and "alpha-male" Dr Karl displaying his dominance with a bloody shoey.

The cameo-heavy video also features Hellions, The Jezabels, DMA'S, Ngaiire, L-FRESH The LION and Flume — knocked out by 9pm.
