What is the name of Mariah Carey's 2005 album that includes 'We Belong Together'?

Mariah Carey’s 2005 album that includes “We Belong Together” is The Emancipation of Mimi. The song became the album’s defining hit and one of the most successful singles of Carey’s career.

The album marked a major return to form after a period of comparatively weaker commercial performance. It debuted at number one on the Billboard 200 and became the best-selling album in the United States in 2005. Its sound blended contemporary R&B, pop, hip-hop, and soul, reconnecting Carey’s signature vocals with current production.

“We Belong Together” was released as the album’s second single and became a landmark recording. It spent fourteen weeks at number one on the Billboard Hot 100 and won two Grammy Awards in 2006: Best Female R&B Vocal Performance and Best R&B Song.

The title can be confused with Carey’s neighboring albums. Rainbow was released in 1999, E=MC² followed in 2008, and Memoirs of an Imperfect Angel arrived in 2009. None of those albums contains “We Belong Together” as its signature studio-album track.
