I was recently looking for Radar Detector and discovered the Triple J Hottest 100 series, which is hosted by an Australian alternative rock radio station. The 2010 instalment yielded the following finds. I didn't know Sia had such verve!
#13: Sia "Clap Your Hands"
#15: Duck Sauce "Barbra Streisand"
#19: Flight Facilities "Crave You"
#28: Darwin Deez "Radar Detector"
#50: Hot Chip "One Life Stand"
#55: Vampire Weekend "Giving Up the Gun"
#56: Sia "Bring Night"
