Participants will complete a series of questionnaires to identify participants' music preferences and participants' sensitivity to reward from musical engagement. The responses from the music preference questionnaires will be used to create a 1 hr playlist of songs by a member of the study team for the participant to be played daily for four weeks. After playlist is created and transmitted to MP3 device, participants will pick up the equipment and a compliance log will be given for the participant and participants' caregivers to confirm adherence to the protocol of daily listening. The platform will be Spotify, where the MP3 device given to participant at the start of the intervention will be preprogrammed with the participant's personal playlist on the platform. This trial is a supplementary treatment option for cognitive and neuropsychiatric assessments for AD, as such no alterations in the current treatment plans of any participant will be necessary.

Examining changes in the NPI-Q which is an informant-based interview that assesses 12 neuropsychiatric symptoms of the participant. The NPI-Q includes 12 neuropsychiatric domains. Initial responses to each domain question are "Yes" (present) or "No" (absent). If the response to the domain question is "No", the informant goes to the next question. If "Yes", the informant then rates the severity of the symptoms present on a 3-point scale where 1 is "mild" and 3 is "severe".

Examining changes in the MoCA which is a cognitive test for Alzheimer's disease. The MoCA assesses different cognitive domains: attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation to time and place. MoCA total scores range between 0 and 30; 18-25 = mild cognitive impairment, 10-17 = moderate cognitive impairment and less than 10 = severe cognitive impairment.

The 20-item Barcelona Music Reward Questionnaire (administered at enrollment) assesses facets of the music and reward experiences with 5 factors: Musical Seeking, Emotion Evocation, Mood Regulation, Social Reward, and Sensory-Motor. Participants indicate the level of agreement with each statement by using a five-point scale ranging from ''fully disagree'' (1) to ''fully agree'' (5). BMRQ total scores range between 20 and 100. BMRQ total scores and NPI-Q totals scores will be used to assess whether these variables correlate. The correlation will be completed via statistical analysis in a chi squared test.
