"Building a Mystery" is a song by Canadian singer-songwriter Sarah McLachlan from her fourth studio album, Surfacing (1997). At a live performance, Sarah explains the song as being "basically about the fact that we all... have insecurities to hide, and we often do that by putting on a facade." She also goes on to say that "unfortunately, if we just be who we are, that's usually the more attractive and beautiful thing".

"I Will Remember You" is a song written by Sarah McLachlan, Séamus Egan and Dave Merenda. The original inspiration came from Seamus Egan's instrumental song, "Weep Not for the Memories", which appeared on his album A Week in January (1990). McLachlan and Merenda added lyrics and modified the melody for her version. The song first appeared on the soundtrack for the movie The Brothers McMullen in 1995 and was released the same year, when it peaked at number 65 on the US Billboard Hot 100 and number 10 in Canada. It was also featured on McLachlan's 1996 remix album, Rarities, B-Sides and Other Stuff. The Rarities version of the song has three verses, the first of which is omitted during live performances, as heard on her 1999 album Mirrorball.
