Listened to the songs as per your brother's request and I liked them. The one with the background harmonies was best, I think. But then again, I like harmony.
As the universe unfolds from moment to moment and events take place that we sometimes make sense of, it's like music. The beating of a metronome, the logic of harmony, and the discord of stuff that we don't understand.
It's all there, in music and I suspect that is its appeal. Music is the echo of the universe.
Good luck Steve.
