How To Search Non-Copy Protected Music CD’s Only Or Even Tabulate Copy Protected Ones

Copy-Protection recently came to limelight as Sony used DRM technology to copy-protect its CD’s which makes them vulnerable to viruses and malware.

This website allows you to search for music CD in Amazon database which do not have any kind of copy-protection enabled. This may come in handy if you want to verify if your favorite music cdc’s are copy-protected or you want to avoid copy-protected cd’s altogether.

Additionally if you want to search for only copy protected music CD’s to tabulate then you can use this site. Personally I don’t see much practical use for this one except for fun.

Note: This may result in blank pages with no content as I am forced to filter after fetching the results. Ideally I should have filtered the results through appropriate query but Amazon API doesn’t currently allow me to do so. I can filter out empty pages which hasn’t been done in this iteration. If enough people are interested I can always add it. This is mainly of concern when searching for copy protected cd’s only.

Technical Note: I used Amazon Web Services API to create them. This is possible because Amazon clearly and consistenly marks copy-protected CD’s in its record.

In a comment in SysInternals Blog, Geoffrey Mack mentioned about this which I subsequently verified.

He mentions about Google search which is rather inaccurate IMHO as it contains lots of extraneous and duplicate results and also doesn’t provide full coverage of amazon database.
