Now Spotify has released data collected from 2008 to the present day and revealed the most-streamed artist from the series, and it's not who you may have originally thought.
Season 5 runner-up Matt Corby is the most popular Australian Idol alumni globally, taking out the crown as the most-streamed artist internationally.
And to think Spotify doesn't even have his 2007 version of 'The Blower's Daughter' on it...
Amassing a huge 576 million streams thanks to his hit singles like 'Brother', 'Resolution', and 'Miracle Love' the singer beat out Guy Sebastian who came in as the second-most streamed artist from the series.
Guy has a hefty 530 million streams worldwide behind him, while Jessica Mauboy came in at third, followed by 2009's winner Stan Walker.
When it comes to Australian-specific listening however, Guy Sebastian nabbed the top spot as the most-listened-to artist locally with 275 million streams, with his song 'Choir' the most-streamed song in Australia from any Idol star.
Spotify Australia's head of music, Alicia Sbrugnera, said despite how many years it's been since the original Australian Idol, the hits from the stars that came from the '00s series continue to gain popularity.
“Australian Idol has grown to become a cultural phenomenon that has, and continues, to shape our nation’s pop and music Zeitgeist,” Alicia said.
“With early seasons gifting the nation with unforgettable moments from Nollsy allegedly being robbed of first place to the first ever double touchdown, it’s evident that Australia’s beloved Idol stars are still a regular part of the nation and the world’s music listening habits.”
