NEW YORK • Nostalgia propelled two artists - one dead, another living - to the top two Billboard spots for music sales.

Rocker Tom Petty roared back on Sunday to clinch the No. 2 position on the United States album chart after his sudden death at age 66 from cardiac arrest.

Demand for his 1993 Greatest Hits compilation catapulted a whopping 2,231 per cent from a week earlier, tracking service Nielsen Music said.

But the 84,000 equivalent album sales still came below Canadian country star Shania Twain's - her first album in 15 years, Now, debuted at No. 1 with sales of 137,000.

Twain, who was one of the most successful artists of the 1990s, wrote an album with themes of personal restoration after a rough spell that included a high-profile divorce and struggles with her voice.

She far outpaced one of the other prominent releases of the week - Younger Now by Miley Cyrus, a return to country roots by the singer who has become better known for her provocative stage persona. Cyrus registered 45,000 sales to sit at No. 5.
