The first single from Hayden Panettiere's debut album, "Wake Up Call," was played on the radion earlier this week.

From there, the Heroes star talked about the songs on said CD.

"They're a little bit eclectic," Panettiere said, describing the experience of hearing her music on the radio as "scary" and "terrifying."

She also said the project changed a bit over the years.

"[The music] changed so much over the years, just because my life experiences and who I am as a person is obviously reflected in the music."

As for season three of Heroes, the cast has completed six episodes already.

"Everyone's so excited about it," Hayden said of the upcoming season, which debuts September 22. "It's the same action, the same high-intensity as the first season."
