A limited number of Muse releases have been released on audio cassette, most of these have been in the 1990s and early 2000s but more recently Muse have released Drones and Simulation Theory on cassette.
Since the 1990s cassettes have largely been replaced by digital CDs as the main music distribution format.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 canceled. Drones was also released on cassette in the US in 2015 and later Simulation Theory was released worldwide on cassette on the Muse.mu store in 2018.
