Online internet store Amazon have announced that they will offer music downloads free of DRM.
DRM or 'Digital Rights Management' technology limits the usage of music you download. For example, you can download a track to play on your PC, however DRM will not allow you to burn the track to a CD or portable music player. If you want music on your portable music player you usually need to ensure the DRM protected music you download allows this transfer, in some cases you might be paying for two downloads, one for PC and one for digital device.
The same applies to Digital movie download, so where you might download a 1GB+ movie file for your PC, you usually get a smaller download for your portable device included. (e.g. www.coolroom.com)
Music fans have a love/hate relationship with DRM - the developement of the technology gives music rights owners no excuse to distribute music through digital chanels, however it reduces the flexibility of the music you own. Hence why I criticised USB music sticks in this post.
Now you know what DRM is, you can see why DRM free downloads are such a great option for the music lover. Still, nothing can compare to buying CDs , artwork + mobile format + the ability to rip to digital.
