Sony Music Entertainment Australia and singer/songwriter Tina Arena have parted ways. Since signing with Sony as a solo artist 10 years ago, Arena has recorded four studio albums. Her worldwide albums sales reach 3.5 million units, according to the label.

Apart from her performance at the Sydney 2000 Olympic Opening Ceremony, Arena is perhaps best known outside her native Australia for "Chains," the 1995 hit which peaked at No. 6 on the singles chart in the United Kingdom.

In a statement, Denis Handlin, chairman/CEO of Sony Music's Australian operations, described Arena as "not only one of Australia's most successful female artists, but also a tremendous ambassador for Australian music abroad."

Arena, who is based in Paris, is recording her next album in Italy. Sources say she is negotiating with Universal Music. A Universal spokesperson did not comment by deadline.
