Sensors, gauges and a valley of products
The sensor, based on your mood while listening to music, automatically creates the music as favorites. But of course the whole thing also works the other way around. You hear music and do not feel really comfortable with the piece. So the sensor marks the piece of music and puts it in the category not so great.
Afterwards, artificial intelligence and machine learning can be used to search for complete music collections for the individual in the future.
With a correct link to the YouTube database, it will be possible to create playlists in a separate area based on the measured mood.
It doesn't sound that difficult at all, nothing on the planet has been researched as much as measuring techniques and measuring devices. Measurements are taken around the clock on the blue planet all the time. Of course also beyond the planet. It is frightening how precisely you can measure today. With the right interface, this great sensor can also be connected to the car radio. A small memory on the measuring device creates a playlist. The car radio anonymously sends the pieces of music with the measurably highest emotions to the radio station or to a company which is specially created for evaluation. The data obtained can be used to target specific commuters with good music in the morning hours. Isn't it nice to only be able to hear good music on the way to work? After recording mood images for a couple of weeks, the data set moves into the home entertainment of young couples and small families. An attempt is made to create an equal mood in the households. The son, the aunt, the grandma and the father take turns listening to the music that everyone likes. Everyone in the household gets a sense of what the other person likes. of course only if all sensors are working properly.
With a central music server that is then finely tuned to all residents of the community by subscription, you only pay for the pieces of music that you officially really like. Isn't it great?
I am happy if my ideas help you on the path of inspiration.
