Amazon has announced plans to create an online music store without copyright protection encryption, reports The Associated Press.

The e-commerce giant made the decision in order to meet consumer demand for music that can play on any MP3 device. All such players support MP3 files but won't play songs encrypted with store-specific protection schemes.

EMI has jumped aboard in preparation for the store's launch. Amazon says 12,000 other unnamed labels will provide songs to the store. They will be announced when it goes live later this year.

EMI also sells DRM-free songs through iTunes.

Pricing in the Amazon store is said to be variable, but the debut is expected to increase price pressure throughout the online music market.
