I watched this too in puzzlement at the order of some of that top 100.
Anthony Callea not only made it into the Top 100 he beat out Crowded House, Powderfinger, INXS, Bob Dylan, The Eagles, even Cold Chisel.
Everyone under #32 which is what "Australia" voted his album to be.
Also there were 4 Female artists - Carol King (18), Missy Higgins (30), Joni Mitchell (60) and Delta Goodrem (80)
Missy and Delta rate a higher mention then Aretha, Cher, Madonna, Billie, Dusty or even Kylie?
Frankly I'm surprised Britney/Christina or Nikki Webster aren't there.
