As Star Trek: Strange New Worlds nears the end of its second season, it has unveiled an ambitious musical episode, a first for the entire Star Trek franchise.

The crew scrambles to find a way to undo this musical condition before it infects the rest of Starfleet, but not before belting out an impressive selection of original songs.
