If someone is concerned that a release is a CD-R before buying from ANY company these days, do not ask the company if it is 'Silver'. Ask the company if the release was 'Replicated' (Glass Master required) or 'Duplicated' (Burned on CD-R). If the company will not tell you one of those words, then they more than likely do not know the difference (which is odd for a label not to know that) or they are being sly with their info. When 'Silver-Bottom CD-R' got popular, it became easy for any company/band or bootlegger to claim their release was in fact 'Silver'. It became a play on words.
