Listen to Faith Hill on iHeartRadio

Faith Hill has set a date and time for the premiere of her new song, "American Heart." She'll reveal the whole song on Twitter on Sunday at 7:00 p.m. ET.

Faith tells People magazine the song is about what it means to be an American in 2012. She says, "We've been through a lot as a country throughout the years, and we've faced tremendous adversity. People are suffering, trying to make ends meet, and times are especially tough right now. The sentiment captures everything I think we all feel when we think about the American spirit."
