D/C or C6 (sus2 b5)?

Hi @swingmix These notes played as a chord can be interpreted in many ways but I would never refer to It as a D Major over C. That would infer a minor 7th over a I major chord in which a bass wouldn’t work. I think a C6 (sus2 b5) or a D7 is the the most accurate way to transcribe. Maybe some theorists here may have some opinions?
