In a way e.g. spotify already tracks your behavior and almost "knows" your favourite song/album of the month. It is technically possible for you to track yourself in an automated manner, no ? If Gorilla or RestGPT can contact several APIs to "put the last Bowie Album" then it could also feed a file of your habits and by there infer on what your favourite album is.
