My advice is to use this information. Music is a great tool to help set or control your mood. Perhaps you need music to help you concentrate, or music to relax to, or music. What is it about these songs that affect us so much? Interestingly, the study of music’s effects on the brain is well documented (and surprisingly much debated).* Experts do seem to agree that, whether “real” or not, music causes the brain to activate in ways that induce emotion.
