Looks like Apple is responding to Amazon's DRM free, 89¢ - 99¢ play - their DRM free tracks will be dropping to 99¢, along with the DRM tracks. They are also adding some Independent labels:

Apple plans to expand iTunes Plus to include certain indie music labels starting Wednesday, October 17 (or sometime this week, at least). This tiny step is encouraging for those of us who like freedom with our music, but it sucks that more of the larger labels are still holding off from hopping on board. This expansion won't include all independent music labels just yet, although we're optimistic that more will be included in the future.

The bigger news on the iTunes Plus horizon, however, is that Apple plans to drop the price of all iTunes Plus tracks. Currently, each track is $1.29 while "normal" DRMed tracks are 99¢ apiece. That discrepancy will be no longer, as Apple will begin pricing all of its iTunes Plus songs at 99¢ apiece (DRMed tracks will also remain at 99¢).

This is the kind of competition that makes most of us smile, even as it makes the RIAA cry.
