There may be more Avicii music to come... According to Variety, Avicii's parents, as well as Geffen Records, have gone through his unpublished music and there could be more than 100 demos still there to be released.
Some of the lyrics go as "It's do or die / But we're alive / And while we're here / Will hold the line." There has been no confirmation of anything being released yet but it could very well happen soon.
This is rumoured to be the lyrics of one of the tracks:
Crossbows and arrows
The smoke in the shadows
You’ll lose your mind
Standing on the battle line
Starting to choke on
Your heart in your throat and
It feels just like
You can’t remember how to fight
We’ll crack before we shatter
We can’t fall apart
We don’t get to die young
Trouble keeping our head sometimes
We just have to push on
We don’t get to give up this life
All the breath in your lungs
Is stronger than the tears in your eyes
It’s do or die
But we’re alive
And while we’re here
Will hold the line
Don’t hold your hands up
It’s your final stand
Put your white flag down
Oh don’t you surrender now
No hero’s story
There’s no blaze of glory
But dawn only comes
At the end of the night
We’ll crack before we shatter
We can’t fall apart
We don’t get to die young
Trouble keeping our head sometimes
We just have to push on
We don’t get to give up this life
All the breath in your lungs
Is stronger than the tears in your eyes
It’s do or die
But we’re alive
And while we’re here
Will hold the line
