I use this when I am knackered but still have to clean up a days worth of mess at the end of the day ( I got six kids) , put this on and your energy swiftly returns.
Allow me to set the scene. Tense as hell D&D session. I have an NPC bard with them who is constantly shattering (not breaking) the 4th wall. They end up in a BBEG fight from hell, and decide to run. Cue the bard using inspiration to give them speed. The song? You're listening to it. We had to take a ten minute break to collect ourselves because we were all stressing from how hard that fight was that the break of this song in mid run broke most of us.
