Italian group Il Divo's cover of the Spanish version of the track, "Regresa a mí", received positive appreciation from critics, who said the cover "has the potential to be a hit and to open doors for many of opera's most acclaimed stars." American alternative rock band Weezer also covered "Un-Break My Heart" in 2005. Their version was released on the album Death to False Metal in 2010. Lead vocalist Rivers Cuomo explained why the band covered the track: "I loved that song. It was actually Rick Rubin's suggestion. We both loved that song and we both thought it would be great for Weezer, and for my voice, and it'd be great to do like a rock version of it with more of an alternative aesthetic. And you know, just the way I would sing it versus in the way Toni Braxton would sing it. And I love the way it came out, and I think probably the rest of the band really does not like it, and that's probably why it didn't make our fifth record, in 2005 when we were recording it." Il Divo's Regresa a mí A cover version of Toni Braxton's Spanish-language version of the song, "Regresa a mí" (Come Back To Me) was recorded and published as a power ballad by the multi-national UK-based quartet Il Divo. It was released in 2004 as the first single from their debut self-titled album. Il Divo manager Simon Cowell bought the rights of the song from Warren. The song was released as the first single from the group's first album Il Divo, released in 2004. The song was recorded at the beginning of 2004 at the Studies Rokstone in London, under the production of the British producer Steve Mac. On
