Could hot new US musical sensation Katy Perry tumble into the ARIA Number one position next weekend? That’s what many in the industry will be predicting after her single ‘I Kissed A Girl’ raced to the ARIA No.2 spot earlier tonight on downloads alone. If she makes it to No.1 next week, she’ll be the second artist in Australian history (behind Rihanna – ‘Don’t Stop The Music’) to go to the top spot on downloads alone. The single has jumped eleven spaces to No.1 on the ARIA digital track chart, curiously also debuting at No.31 on the same chart and has moved up from No.13 to No.2 on the official singles chart. Given the track’s extraordinary performance so far, expect Katy to hit the number one spot next week. The CD single hits stores on July 14, followed by the album ‘One Of The Boys’ on August 02.
