Origin of Symmetry (lost unreleased songs from Muse album; 2001)
Origin of Symmetry is the second studio album by English rock band Muse, released on July 17th, 2001. There are multiple missing tracks on it.
In an interview with lead singer and guitarist Matt Bellamy conducted on February 15th, 2001 on the Muse fansite microcuts, Bellamy stated the following:
“So far, tracks in the can include Bliss, Hypermusic, Origin of Symmetry, Love Bleach, Shrinking Universe and Razor Song plus, of course, their forthcoming single, Plug In Baby, which hits the shops on March 5th through Mushroom.”
The tracks "Bliss," "Hyper Music," and "Plug In Baby" were all released on the album, while "Shrinking Universe" was released as a B-side of "New Born." Three tracks mentioned here, however, have possibly never seen the light of day - "Origin of Symmetry," "Love Bleach," and "Razor Song."
It is common practice to use working names, so this may be the fate of these tracks. "Razor Song" was presumably renamed to "Screenager" (as one of the working titles for that, seen on a live setlist, was "Razor Blade."  Obviously, these tracks couldn't be "Bliss," "Hyper Music," "Plug In Baby," "Shrinking Universe," or "Screenager."
