Are you saying that some or all of :
1. Billie Jean live, Michael jackson
2. Thriller, Michael Jackson
3. Smooth Criminal, Michael Jackson
4. Rhytm Nation, Janet Jackson
5. I Want You back, Jackson 5
are one defining move?
And perhaps in Australia, but in America, definitely I Want You Back is more iconic, so it might just be a difference in locations. Even Michael on his 30th Anniversary took it back to perform the song just like they did on the Ed Sullivan show.
