The ultimate communication through any piece of music is the consciousness of both composer and performers: their attitudes, their emotions, their dreams and their approach to life and love.
How you receive this communication will be modulated by your own conditioning with regards to the peice. For example: a love song may have come from a place of celebration and joyfulness in the composer, but if it reminds you of your sadly departed lover, it may bring up feelings of sadness instead.
Music is a great addition to your wellbeing toolkit because it acts on consciousness more directly than most other mediums of communication. Music is a vibration that bypasses mental, rational and conscious defenses to affect us on an energetic level, often regardless of things like genre and lyrics.
I hope you enjoy getting musical this week.
