Essay writing music is essentially Trance music - well, OK - that might be a little broad but really, what we're talking about is music that you can fall in to, that doesn't freak you out, that becomes familiar quickly & allows you to get lost in your own thoughts.
Before I write up anything for this playlist I spend a few hours listening to the same track on repeat - to see if it works - to see if I can write to it and whether it pulls me out. This track is brilliant - you should have seen the amount of email I conquered while listening to it!
The track just builds and builds - bringing in different instrumentation, different energies and doing so in a way that is instantly familiar and accessible and just - yeah... ;-)
You should take it out for a spin.
