Nemo (song) stated that the title is Latin for "nobody" and the song is based on his occasional feelings of being lost, longing for the past and feeling nameless. This contradicts speculations that the song simply borrows on a Nemo character of an earlier work, such as J. Verne’s Captain Nemo, Homer’s Ulysses alias Nemo, C. Dickens’ Captain Hawdon alias Nemo, W. McCay’s Little Nemo, or the Disney Studio’s film "Finding Nemo". Asked about that T. Holopainen responded: Nemo is the most played song by Nightwish, with well over 500 times as of March 2018. "Once" topped the album charts in Finland
