"Burning Heart" is a song by Survivor. It appeared in the 1985 film Rocky IV, and its soundtrack album. It was also released as a single, and peaked at #2 in February of 1986.
Jimi Jamison re-released "Burning Heart" on his album Empires. On the album the song's title was misspelled as "Burning Hart", presumably to avoid legal troubles.
