It is always about the music.  I could never understand music collectors who have thousands and thousands of pieces of music (LP’s, cassettes , CD’s, etc).  How you store the music in an accessible fashion is another question.  There is a point your collection becomes unwieldy.  I never collected for the sake of collecting.  It was always about the music.  Each person has the same limitations:  you can only play one piece of music at one time.  Besides when you have too much music too much becomes undiscovered or underplayed.  The best music gets played over and over.  My collection is always about the music.
