I am fortunate to have a New/Used store near by. I have found that some of my "losers" generate enough value to pick up something new (or used, but new to me). The ones that are just plain crap are donated to Salvation Army and end up next to Montovani's Christmas Music 1964
Throw it out!
I just discovered a technique that will save a lot of aggravation. When I find a record that is not satisfying me sound-wise (or sometimes musically,) I dispose of it or relegate it to the inactive file. Rather than having it available in my collection to aggravate me, it gives me great satisfaction to get rid of it!
