PMIEdit a song above, capture it as A or B; the key is auto-estimated (you can
listen to the two candidate keys and pick the one that sounds right — fewer accidentals — or set it manually).
A captured song can be brought back with ✎ Edit and re-captured to update it. With both captured, compute PMI.
