Franz: this is a difficult and complex debate. If someone bought an *audio* CD of mine, and *did not make a copy first*, then certainly they could re-sell it. The CD is the product in itself. (This is the simplest and most common example, but not really what we are talking about when discussing sample CD's etc.) If however I produce a CD of Mood Music or Production/Library Music. That CD is not sold, but given to production facilities for free. If someone uses a track off that CD, they are required by law to log the usage and submit a cue sheet to their local Mechanical and Performance Copyright societies. This music is never actually sold - it is licensed. If the user fails to log usage, I lose money. The CD in itself has no value at all. Let's say now, I made a sample library CD, and Joe Bloggs bought it. I *licence* him to use the samples in any of his productions. The CD has been bought but the samples themselves are *never sold*. Joe uses the sounds for a while, then decides he wants to get rid of the CD. He sells it to Jill Spriggs, who now uses the samples (which she does not own) for her productions. She never obtained a legitimate licence from me, so her use of my samples is an infringement of copyright and illegal. So....it's not just as simple as selling stuff on Ebay. Each scenario has its own complications..... Regards - Colin
