Is it not true that liking a specific band, song, or kind of music is simply remembering the fact that you liked them a moment ago? a year ago? If everything is but a fleeting moment, your love for music only relates to the person you were then. Perhaps jazz put me in a state of ecstasy an hour ago while this other techno loud beat-filled music is inspiring me now.
So how can anyone ever tell another what music they're into?
