We're all just passengers of time.
Our lifespan is so small compared to the infinite time of the universe.
No matter what we do, the time will always go on and there's nothing we can do to change it.
What we can do is to make our life really matter every single moment.
Passengers of time is actually the first (and probably best) part of Mars, a very very old song of mine. I played it again now, with much better instruments, and much more feeling and released it for you to listen.
Hope you'll enjoy it.
