Abstract: The present invention advances the state of mood-inducing music and sound technology by incorporating selected combinations of factors to create recordings, each having specific mood-inducing profiles for a user. Recordings may be stored in novel personal listening devices, such as headsets or earphones, and the selection for play of one recording to induce a desired or appropriate mood may be made by the user using the device itself, an app connected to the device, or may be automatically selected for the user using brain-sensing feedback technology.
