In this case they got the notes exactly right, they just didn't indicate in the key signature that there was a Bb, Eb, Ab, Db, and Gb. Thus every time one of those notes showed up, it was shown as an accidental. I just don't like clutter, and I like things to be easy to read.in my experience, i think when that happens, they gotta have some program that picks out the notes or something and it probably defaults to c major with no sharps/flats. i have never found out if there is a program for this but i have wondered about it for a very long time, especially when ive found arrangements that are physically unplayable. rearranging a crappy arrangement is good tho, cuz if the notes are right then you can still do something with them so you can actually play it
i dont mind accidentals tho, at least as a piano player, cuz im really dumb with remembering my black keys
That said, even with the right key signature, there's accidentals all over the place in music, like Death's song "Crystal Mountain." General key signature is D minor, with one flat, Bb, but there's accidentals all over the place because Chuck Schuldiner (RIP) was really influenced by jazz.
I just like things to be clear is all.
