Congratulations on your new series, it provokes stimulating thought yet is highly enjoyable and satisfactory.
I caution you though, do not make dangerous assumptions about this 'mythical' 2000. Whilst silver space suits seem perfectly feasible, would a Bassoon REALLY still exist in this year we call '2000'?
I personally believe music will enter a subliminal state. We shall only experience a mild sensation of alternating current but it will enter our subconscious and remain there until an appropriate time.
I propose this 'invisible' sound to be named 'musAC'.
