Remixed features mostly new remixes of songs which originally appeared on McLachlan's studio albums: Solace (1991), Fumbling Towards Ecstasy (1993) and Surfacing (1997). Three tracks were previously released on club compilations or 12" promotional singles: "Possession" (Rabbit in the Moon Mix) in 1995, "I Love You" (BT Mix) in 2000 and "Sweet Surrender" (DJ Tiësto Mix) in 2000. Remixed also features "Silence" by Delerium and McLachlan, which became one of the greatest trance songs of all time. Here, it was remixed by Tiësto. The remix album was overseen and produced by George Maniatis.
