The inevitable degradation of vinyl is its downfall.

And, in some cases, the degradation has occurred before you even slit open the shrinkwrap.

In the 60s and 70s, at least, there were labels notorious for the crappy quality [sic] of their pressings -- it was nearly impossible to buy an album on that label that wouldn't skip or have built-in Rice Krispies or whatever. (And far fewer labels with a reputation for releasing smooth, immaculate pressings.)
