Singer Bonnie Tyler dead at 75

Bonnie Tyler, the husky-voiced singer best known for the 1983 smash Total Eclipse of the Heart, has died at a hospital in Portugal. She was 75. 

What's happening: Tyler was hospitalized in early May in Faro, Portugal, where she lived, for emergency intestinal surgery and was later placed in an induced coma. She died  "unexpectedly" Wednesday night, according to her family. 

Why it matters: The Welsh-born singer repeatedly hit the charts in the U.K., Canada and the U.S., but is best known for Total Eclipse, a power ballad and rumination on lost love that has never really gone away — passing one billion video views on Spotify and having been covered by the likes of Nicki French, Westlife and One Direction. She had another hit with 1984's Holding Out For a Hero and a year later with Here She Comes.
