It's the part of the show where it all fades away
When the lights go to black and the band leaves the stage
And you wanted a encore but there's no encore today
Cause the moment is now, can't get it back from the grave

from Macklemore and Ryan Lewis (Ft. Macklemore) – Ten Thousand Hours Lyrics on Rap Genius

Meaning

At the end of the concert sometime the band will come back out and play another song, sometimes not. Macklemore is using a metaphor to state that you might get another opportunity to live again tomorrow but you might not so live it like your last, you can’t get today back from the grave.

Carpe diem, the original YOLO.

The show that Macklemore is referring to is a metaphor for a person’s life. When facing death, everyone wants a second chance — a little more time to accomplish what they could have. But there are no encores in real life — when the lights fade, you die, and the band won’t be coming back to play. Using the word “grave” further evokes death imagery and solidifies the metaphor.

Compare Shakespeare’s ‘Tomorrow’ speech from Macbeth, Act 5, Scene 5, lines 17-28.

She should have died hereafter;
There would have been a time for such a word.
Tomorrow, and tomorrow, and tomorrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more.
It is a tale
Told by an idiot, full of sound and fury
Signifying nothing.
