CD-Rs will die faster than a Silver-Pressed CD because of the dyes used for duplication and the info floating on the surface. Silver-Pressed CDs have their info stamped on so they will last longer. Also, with CD-Rs, if you are printing artwork on them using one of those disc printers, the printer ink is shit and eats away fast. Some people also use those glue labels or go 'Sharpie' crazy on CD-Rs not knowing the label glue and marking pen ink is very damaging and eats through the surface also. Some of the cheaper CD-Rs start rotting fast and data/audio is lost within 2 years. So...that cool band release on CD-R you have in your collection will not be cool for long.
