A limited number of Muse releases have been released on audio cassette, however none have been released in the UK since Origin of Symmetry.
Since the 1990s cassettes have largely been replaced by digital CDs as the main music distribution format. Muse cassette releases were thusly produced in considerably smaller numbers than their CD counterparts. The format remains popular in countries such as Indonesia, where Absolution and Black Holes and Revelations have been released on cassette.
In the UK, four Muse releases were made available on cassette, namely Showbiz, Origin of Symmetry, "Unintended" and "Plug in Baby". "Muscle Museum" was due to be re-released on cassette, but this was later cancelled.
