Glassheart (song)
song performed by Leona Lewis
"Glassheart" is a song recorded by British singer-songwriter Leona Lewis for her third studio album of the same name (2012). The song was conceptualised by Lewis and frequent collaborator Ryan Tedder at his family home in Denver, Colorado. As she was experiencing a stressful time in her life, Lewis wanted to create an uptempo dance track with Tedder as she felt a ballad would make her more upset. It was co-written by Lewis and Tedder alongside Brent Kutzle, Noel Zancanella, Justin Franks, Fis Shkreli and Peter Svensson. Production of the song was handled by Tedder and Franks, with the latter credited under his production alias DJ Frank E. It was co-produced by Zancanella, Kutzle and Shkreli.
"Glassheart" is an up-tempo dance song that incorporates elements of dubstep, grime and house music. Lyrically, it is about a woman's fear that her boyfriend will leave her and thus she protects her emotions and her heart from breaking. The song received positive reviews from music critics, many of whom praised the musical direction and its grimy, dubstep breakdown. Upon the release of Glassheart, the song debuted at number 27 on the UK Dance Chart due to strong digital download sales during the first week of Glassheart's release. It debuted at number 167 on the UK Singles Chart.
This brief starts where responsible research should: with the source description of “Glassheart (song)” as song performed by Leona Lewis. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the arts & letters register because the source frames it as song performed by Leona Lewis. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Aug 31, 2025. The linked authority identifier is Q2092465. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2012.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
