I started playing osu a few months ago, one of the first things I did was to remove the hitsounds, I find them misleading and they almost never sound good with the songs (having been a musician, it particularly bothers me to hear a sound that was evidently not conceived by the creator of the piece, but this is just a personal preference). I recently decided to start mapping, and in the process I also came across the ranking criteria and discovered that hitsounds are mandatory for a map to be considered... so I ask myself: what makes hitsound so important? How many of you play with hitsound and why?
