Adia

"Adia" is a song by Canadian singer Sarah McLachlan from her fourth studio album, Surfacing (1997). It was co-written by McLachlan and her longtime producer, Pierre Marchand. McLachlan has said about the song, "...more than anything, it's about my problems in dealing with feeling responsible for everyone else". "Adia" was released as the third North American single from Surfacing on 2 March 1998; in Europe, it served as McLachlan's debut single, receiving a UK release in September 1998.

"Adia" was McLachlan's first top-five song on the US Billboard Hot 100, peaking at number three, totalling 14 weeks in the top five, and ending 1998 as the country's 20th-most-successful song. The song also performed well in McLachlan's native Canada, peaking at number three for three non-consecutive weeks on the RPM 100 Hit Tracks chart. The song's music video shows McLachlan singing directly to the camera in various public places, including a busy intersection, an office lobby, a supermarket aisle, and in front of a store that sells wedding dresses.
