have you ever worn a record out through DJ-ing it or listening at home? i know we all have bought records that were previously owned by non-collector types that have been "worn out" or simply trashed (not stored properly, not handled properly, etc), but have you ever had to replace a record because you simply spun it to much?
in other words, have you, as a "serious" record person, bought a M- copy of something and noticed after awhile that it sounded/looked VG?
couple sub-points:
a) I know people are concerned about back-cueing records (so they don't get "cue burn"). what do you feel about that?
b) you ever loaned a record out to friend and gotten it back in noticably worse condition?
c) have you ever bought multiple copies just to hedge against wear? (not to get different label designs, issue/demo, UK/US/Canada pressings, etc)
...or are we all just being OCD, and since we all store and handle are records reasonably well - they should (barring fire, accident, etc) last our lifetimes?
