This is a different proposal. The idea is to see how creative an AI can be. The rules are simple and general, leaving a lot of room for "creative license".

I call this the "Sad To Say" test. It involves the use of excitement and regret represented by a story about an event somewhere in a persons lifetime. The underlying idea is to capture emotional stresses and strains. The whole album has a common structure and theme.

Billy Joel wrote a song "Scenes From An Italian Restaurant". https://www.youtube.com/watch?v=Hxx8IWIvKg0

The structure of the song is in three parts, the "headboard", the "mattress", and the "footboard". This structure is called an HMF (headboard, mattress, footboard).

Create a music album with 12 songs. The overall album structure is 12 different people who have gathered for a 50th year reunion. Each person tells a story using the HMF structure.

The overall theme of the album is a collection of stories of great potential, explained in the mattress section, to a group of people who know each other from high school or college.

Each song's "headboard" involves a setup story using a tempo and conversation structure similar to the Billy Joel example. This same tempo and structure will be repeated in the "footboard". The "headboard" should lead to a sense of "great potential".

Each song's "mattress" is a completely different tempo and structure. The tempo is different. Each mattress song should be about an event with great potential such as a love interest, a business success, an athletic achievement, etc. The story should emphasis a great rise of success that eventually fails.

Each song's "footboard" should return to the "headboard" tempo and conversation structure. The "footboard" will recap the "mattress" theme ending with the phrase "Sad To Say..."

Success will be measured by publishing the album in standard music channels and looking for listener approval. True success would be a top 10 song or album.
