Panettiere was on KISS-FM, hosted by Ryan Seacrest yesterday (July 15).
The Heroes star let fans hear the first track off her debut yet-untitled album. Panettiere admitted she was nervous about hearing her song on the radio.
The 18-year-old actress announced that her musical taste is very diversified ranging from Pavarotti to rapper Nas. Her wish for the disc is simply "to make sure that the music didn’t all sound the same."
Panettiere has done some work on soundtracks including Cinderella III: A Twist in Time and Bridge to Terabithia.
