This is what I play as a basic bass line for Midnight City by M83, 
it may be incorrect but it fits well enough when I play the song, 
comment corrections if there are any or completely alternate basslines.


0:00 - 0:18

|-3---------------5-------0-------|


0:18 - Onwards with pauses when necessary
|---------------------------------|

|---------22-22-2-----------------|
|-33-33-3---------55-55-5-00-00-0-|


repeat as necessary this pretty much goes for the entire song, 
there is also room for improvisation which can warrant some cool
results.  

Enjoy.
