Star Trek: 10 Times Music Saved The Day

3. We Are One - Subspace Rhapsody

Though it would have been very easy to slip the actual Star Trek musical in at number one on this list, it did feel a little cheeky. Let us instead concentrate on just how much fun - and critical to the plot - We Are One was in Subspace Rhapsody.

The magical MacGuffin (the subspace fold, and the required 344 giga electron volts) aren't really the point of the episode, though they combine to inspire the final, uplifting showstopper. Uhura has the crew of the Enterprise - and Garkog's crew aboard the Klingon D-7 - join in a song about the importance of working together and feeling part of something bigger.

It raises the audience's spirits, as well as the voltage, shattering the subspace field and ending the musical episode. Without it, one could imagine the music would still be playing somewhere...

This news really changes everything...
