In what can only be described as news I meant to write about days ago, the New York Post recently reported that Amazon.com has targetted mid-September for the launch of its DRM free digital music store.

The current thinking on a launch date for the Amazon MP3 store is the week of Sept. 17. However, industry insiders aware of Amazon’s plan caution that it remains a moving target. Amazon has already pushed the timetable on the service’s introduction multiple times.

The service is expected to carry somewhere around 1 million tracks at launch, featuring music from Universal Music Group, EMI and a large number of independent labels.

But it will be missing music from two notable sources, Sony BMG and Warner Music Group. [NYPost.com]
