"Heartless" is a song written and recorded by the rock band Heart in 1976 for their album Magazine. Issues with the band's previous record label Mushroom caused a delay in the album's release and "Heartless" was released as a single two years later, after the re-issue of their first single "Crazy on You".
The song is an aggressive hard rock number that opens with a slower synthesizer based interlude before opening up into a full hard rock tune. The lyrics involve a scorned lover who apparently can't get away from the grasp of her heartless partner. "The doctor said come back again next week / I think that you need me / All she did was cry / She wanted to die doctor when can you see me / There's a guy out there / Seems like he's everywhere / It just ain't fair."
"Heartless" and "Without You" were the only singles released from Magazine, with "Heartless" peaking at number twenty-four on the US Billboard Hot 100. Only five months passed before Heart released their next album, Dog and Butterfly.
