How much music is enough?

I've been sampling the Bach box and I pronounce it worth buying.  Compared to the available full-price recordings, I give it a 7 out of 10 and that is for 65 cents per disc.  The sound is generally quite good, the performances of the chamber music are excellent, the harpischord occasionally stale (I prefer Bach on piano), the masses and passions are above average, and most of the cantatas are "good enough."  It won't displace my very favorite Bach recordings, but these make good second choices pretty much across the board.  To be frank, even among experienced classical music listeners, no more than one person in ten can tell the difference and yes that means you.

Yesterday Jane Galt asked "how much music is enough."  Ha!  But two days earlier, after receiving the new Amon Tobin CD, I vowed not to buy another CD for an entire year.  It's not a question of money, rather I am looking for a new listening experience.

Let's see how long I last, I'll let you all know when I snap.
