What makes a song catchy? Why do we hum some tunes endlessly for days at a time while others just pass on through one ear and out the other? I have no idea. We’ve considered this phenomena on this site previously, and still have not discovered the scientific reasoning behind it. That being said, this session here is another very prime case study that we will no doubt be sending off to esteemed laboratories for in depth research into the inner-workings of the human mind as to how it retains musical compositions. We’ll let you know our findings when the results are in. Until then, best of luck getting these songs out of your heads.
