Karise Eden's unleashing of "the beast" on The Voice on Sunday night has seen her grand final performances shoot straight to the top of the iTunes music chart.
Her rendition of Hallelujah last week has also entered the ARIA singles chart at number two. It sits behind Whistle by Flo Rida.
Eden's cover of Ruby Turner's Stay With Me Baby during the last competition round on the hit TV show is already at number one on the iTunes top ten singles list - less than 24 hours after her stand-out performance.
Her original song I Was Your Girl is number two, followed by her cover of Hallelujah at number three.
Lionel Richie's duet with coach and son-in-law Joel Madden during the grand final live show impressed his fellow coaches.
"Lionel Richie and Joel Madden. How COOL", Keith Urban tweeted.
Delta Goodrem was left gushing, "thank you both for sharing that wonderful performance with us all so special"
Eden is the firm favourite to be named the winner of the Nine Network's singing competition on Monday night, ahead of the other finalists Sarah De Bono, Rachael Leahcar and Darren Percival.
