I'm seeing more and more music that contains conflicting or erroneous information - for example, C°7 written with an A, (not B♭♭), or E7♭5 with A♯ (not B♭).
Wondering if it's just ignorance, or whether writers try to come up with what they consider easier to read dots. It's in all sorts of publications, from printed sheet music (different publishers) to 'educational' books.
This may get thrown out as subjective, but there could be good reasons for it - maybe computer programs don't help? And the bottom line - does it really matter?
EDIT: yes, it has to be the publishers ultimately, but there's a distinct possibility that they merely print what they're given, therefore I can't hold them totally responsible. Not entirely convinced by the title edit.
