EFF reports that according to Ars Technica Apple is embedding a extra data into its new DRM-free music files including the name & email address of the purchaser. Tests done by EFF did not reveal any audio watermarks through comparison of waveforms of the original file and decoded PCM/WAV versions. However in one case, the difference in file size showed the iTunes file was bloated by 320kbits.

The obvious concern is that somehow the embedded data could be used to track back shared music to the original owner.  From Ars Technica:

The big question, of course, is what might Apple do with this information? Because it can be spoofed, it’s not exactly the best way to determine who is sharing music, and in any case, tracing a link back such as this would leave a copyright holder in a gray area. Embedded data or not, the mere presence of the data in a file found on a share is not an unassailable indicator of copyright infringement.

Today Apple launched iTunes Plus which offers the updated EMI catalog in 256 kbps AAC DRM-free glory. One of the coolest new features they offer is the “upgrade your library” feature which scans your current library and then determines what EMI catalog you already own and then you can re-download the tracks to the new DRM higher quality versions. All you need to do is pay the $0.30 difference for each track.

This episode we feature music from the three digital-only releases by ambient pioneer Robert Rich. These releases were recorded at two concerts in San Francisco produced by Dub Beautiful Collective. Each set gives the listener a taste from most phases of Rich’s 20+ year recording career, and feature performances of effected steel guitar, bansuri, and a 12 minute improvised piano solo by Rich the likes of which have never been released. Live at Fort Mason [sets 1 & 2] and Live at Morrison Planetarium are available only at Fake Science Music Store.
