Pink! is officially the most popular artist on Australian radio, again.

For the fourth successive year, the U.S. pop star has topped the "Most Played Artist Report," published Wednesday by the Phonographic Performance Company of Australia (PPCA), Australia's primary performance rights agency.

Pink! nudged Lady Gaga into second spot while the Black Eyed Peas grabbed third spot, having missed a top-50 position in 2009.

Nine homegrown acts appear on the list, down from 13 in the previous year. The Australian charge this time was led by recently-disbanded Powderfinger at No. 6, rockers Jet at No. 7, and Guy Sebastian at No. 10. Just six British acts appeared in the top-50, led by 17th ranked Lily Allen.

U.S. acts dominate the chart, accounting for 28 of the top 50.

Sebastian, whose star rose when he took out the inaugural 2003 edition of "Australian Idol", was a winner all over again in 2010. His chart-topping track "Like It Like That" was No. 1 on the "Most Played Recording Report." U.S. artist Owl City's arrived at No. 2 with "Fireflies", while The Black Eyed Peas' "I Gotta Feeling" took third spot. Jet landed at No. 4 with "She's a Genius" while Australian pop singer Vanessa Amorosi rounding out the top 5 with "This Is Who I Am".

All told, domestic talent accounted for 24 of the top 100 "Most Played Artists", up from 22 in the previous year. American acts again dominated, accounting for 52 of the top 100 most played recordings.

The PPCA's reports were measured by collating titles that appear in its broadcast log for the period July 2009 to June 2010.
