I think the Guideline "All circles and slider heads should be snapped to distinct sounds in the music. Adding hit objects where there is no musical cue to justify them can result in unfitting rhythms." should be changed to a Rule because I think it's one of, if not the most important "rule" every mapper should follow. The map that first got me looking up this rule/guideline is beatmapsets/659328#osu/1442631 this map Aeril's Expert diff. At 00:37:121 there is a burst that so blatantly doesn't follow this guideline by having a burst on 1 trumpet note. There are more maps that brake this guideline but not as noticeably (still shouldn't be allowed) and some maps had to change triples because "no distinct sound". So essentially you could just place random objects on the map (which by these rules would be rankable) and hope for BN RNG.
Conclusion: I don't want more maps in osu! that don't follow the music/have objects in the map that don't correspond to any sounds in the music so I think that guideline should be changed to a rule.
