It’s not just a sweet, sweet fantasy, Lambs. Mariah Carey celebrated 30 years of Daydream on Friday, releasing a fully expanded edition of the 1995 album via streaming services. The original spent six weeks atop the Billboard 200 and was later certified 11x Platinum, and this anniversary version builds on that legacy with a run of previously unreleased material.

Daydream: 30th Anniversary Edition, out now via Columbia Records and Legacy Recordings, is built around two previously unreleased writing demos: early sessions for “Melt Away,” written with Babyface, and “I Am Free,” written with Walter Afanasieff, which Carey has reportedly sat on for decades. Rougher and less certain than the finished versions fans know, they give us a rare look at the songs before they became hits.

The rest of the expanded edition adds fan-favorite deep cuts, live recordings, era remixes, and a new remix of “Underneath the Stars” by Eric Kupper. Recordings of ‘Always Be My Baby’ and ‘Open Arms’ from a 1996 Rotterdam show, never before released, are included on the CD edition, and the vinyl release includes her full 1995 Madison Square Garden concert for the first time.

An unreleased “Making of Fantasy” short feature documents the video Carey directed entirely on her own, and it premieres on her YouTube channel on July 20, offering a look back at the single that made her the first woman to debut a song at No. 1 on the Hot 100.

The chart record holds up on its own: three Hot 100 No. 1s, a 16-week run at No. 1 for “One Sweet Day,” and more than 27 million albums sold. What the writing demos add is something the numbers can’t: a version of Daydream before anyone knew it would become what it became.
