These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Older Than They Think: Contrary to popular belief, the concept of video game music remixes and a central location to showcase them was not originally conceived by OC ReMix. The site's founder, David "djpretzel" Lloyd, was actually inspired by specialized sites like C64 Audio, back then a collection of free Commodore 64 arrangements.
The Scrappy: Vocal ReMixes are often the point of ire, mostly for those who prefer instrumental-only music (most VGM is instrumental), consider video game music with lyrics to be out of bounds, or dislike the quality of the vocal performances. They seem aware of it, as their 2012 April Fools' Day joke involved a Re Tool to all vocal remixes.
You Keep Using That Word: Because OverClocked ReMix sounded better than "OverClocked Arrangements," the site uses the proper noun "ReMix" (capital R, capital M) to signify interpretive arrangements rather than traditional remixes. Though OC ReMixes almost never directly sample the original audio, most people casually refer to them as "remixes" anyway.
