Amazon.com, Inc. today launched a public beta of "Amazon MP3," a new digital music download store offering DRM-free MP3 music downloads.

Amazon MP3 has over 2 million songs from more than 180,000 artists represented by over 20,000 major and independent labels.

"Amazon MP3 is an all-MP3, DRM-free catalog of a la carte music from major labels and independent labels, playable on any device, in high-quality audio, at low prices," said Bill Carr, Amazon.com Vice President for Digital Music. "This new digital music service has already been through an extensive private beta, and today we're excited to offer it to our customers as a fully functional public beta. We look forward to receiving feedback from our customers and using their input to refine the service."

Every song and album on Amazon MP3 is available exclusively in the MP3 format without digital rights management (DRM) software. This means that Amazon MP3 customers are free to enjoy their music downloads using any hardware device, including PCs, Macs, iPods, Zunes, Zens, iPhones, RAZRs, and BlackBerrys; organize their music using any music management application such as iTunes or Windows Media Player; and burn songs to CDs.

Most songs are priced from 89 cents to 99 cents. The top 100 best-selling songs are 89 cents, unless marked otherwise. Most albums are priced from $5.99 to $9.99. The top 100 best-selling albums are $8.99 or less, unless marked otherwise.

Every song on Amazon MP3 is encoded at 256 kilobits per second.

Amazon's customers can purchase downloads using Amazon 1-Click shopping, and with the Amazon MP3 Downloader, seamlessly add their MP3s to their iTunes or Windows Media Player libraries.
