The track was released before the Infest the Rats' Nest announcement and before the bands fourteenth album, Fishing for Fishies came out.

[2] The song's notable switch into thrash metal and lack of inclusion on Fishing for Fishies started a rumor that a new album was on the way.

This rumour was confirmed on 30 April 2019, on a Reddit question-and-answer, in which the album was revealed and that it would include "Planet B".

[7] Similar to the rest of the tracks on the album, the lyrics deal with the environment and its mistreatment, along with climate change, featuring the line "there is no planet B".

[1][7][8] The track was released alongside a music video, in which the seven members run around an empty highway in all orange "barking like dogs", "smiling demonically", and dancing until the ending in which a stranger shoots the members and lights them on fire.
