So says a story on Billboard.biz: Amazon.com’s (NSDQ: AMZN) online DRM-free music service could launch as soon as Tuesday next week, depending on whether CEO Jeff Bezos gives final approval after an internal presentation. Of course, if he doesn’t like it, it could be delayed again. NYP reported on a mid-Sept launch last month.

The MP3 tracks will only be from EMI and certain releases from Universal Music Group, and indies…Warner Music Group and Sony BMG are still the holdouts on DRM, though probably not on the service itself. Amazon also is planning a tiered pricing scheme: four different ones, says the story.
