Aftersong and the plain AI list
The plain AI list is run through the same rules as the card. Aftersong's own checks for years and connection are enforced in code, so they hold by construction and are not offered as results.
| Set | Aftersong cards built | Plain AI passing | Outside the years | Not in Qloo | Aftersong personal items |

OP-01
Said the app was easy to understand and reported no moment of confusion. No criticism was reported.
OP-02
Faced some small difficulties at the start and got used to the app.
OP-03
Was confused and felt lost at first, and understood the app by the second day.
Session held 2026-10-29. These are the participants' own reports about ease of use. They are not a measure of benefit, and no claim of benefit is made.
Both error directions
No human error review was carried out before submission, so there are no counts and none are claimed. A review of both what Aftersong rejected and what it kept is planned after submission.
Misses, by form
No misses recorded. Every form in the curated set built a card.

Review summary page read 2026-10-28 via search result: 22 studies, 1,972 people. The size of any benefit was not confirmed, so none is claimed.
Music memory
A 2015 study in Brain compared brain regions that hold long-term musical memory with Alzheimer's data and found they lose fewer neurons and show less metabolic decline than the rest of the brain.

Citation and findings read 2026-10-28 from the Duke Scholars record and press coverage. Small sample; the paper's aim of therapeutic use is stated as a hope, not a result.
Ages 10 to 30
People tend to recall more personal memories from roughly ages 10 to 30, the reminiscence bump. A systematic review of 68 studies puts the span at about 10 to 30 years for important events and about 5 to 30 for word-cued memories.
