Who would have thought that a slow jam could be so uplifting?
The song might seem gloomy, and the title ends with the words "It's Over".  However, there's no comma in the title.  It's not a command to stop dreaming, because it's over.  It's a request to not dream THAT it's over - there's a long road ahead.  
Let's not even talk about how this is arguably the greatest song ever composed by a New Zealander - it is most certainly the biggest international hit by someone from that county.  Just soak in Neil Finn's lyrics.  
Now that you heard this, go to Totally Covered for a great version that respects the local New Zealand culture.
