I'm not really a picky guy but some of the CDs that I received are way too bad to be graded as 'excellent'. Some CDs have so many lines and marks that I feel counting my moustaches would be easier than counting those lines

.
Most of these bad CDs I got from Germany (some from US). People in UK seem like they can take care of their stuff pretty well. And they usually grade their CDs in a more professional manner.
Yeah, those sellers who sold me 'bad' condition CDs most of them have solid feedback ratings. Some I can see buyers gave comments like "Great stuff!!! Excellent.... blah". That's why I wonder is it that CD collectors usually don't give a fuck about CD condition?
Well, I'm NOT going against those sellers in Germany or US or anywhere. There's a seller even gave me positive feeback before I received his stuff so I'm quite sure he doesn't really aware (or care) about the bad condition. Those sellers can be some 'nice' people too but their grading criteria is something that I can't really judge.
By the way, to me 'plays fine/perfectly' means the CD is playable, it means nothing about the condition of the disc. I can rub my CD on floor and still it plays perfectly
