Microsoft has announced its plans to bring Xbox Music to iOS and Android devices, as well as free streaming on Xbox Music via the Web.

Microsoft said that in the coming months, additional updates for iOS and Android platforms will become available, including an offline mode that lets you save your music to your device for playback without an Internet or data connection.

With this access to Xbox Music grows to include iOS and Android devices, as well as a free Web-based interface on computers.

“Xbox Music now, more than ever, powers music experiences between Windows 8, Xbox, Windows Phone, and now iOS, Android and the Web,” said Jerry Johnson, general manager of Xbox Music. “We’re also excited to connect artists with their fans on the most anticipated consumer product of the year when Xbox One launches Nov. 22.”

“Starting today, your Xbox Music Pass brings the catalog of music to iOS and Android devices. Get unlimited access to the songs and artists you want at any time with playback across your tablet, PC, phone and Xbox console for $9.99 per month or $99.99 per year”, Microsoft said in a statement.

Add a song to your collection on your Xbox, and you’ll also have that song on your iOS, Android or Windows 8 device on the go or at the office. Xbox Music Pass also unlocks unlimited access to tens of thousands of music videos on your Xbox 360.

With the addition of free streaming on the Web, enjoy on-demand access to 30 million songs globally for free on the Xbox Music Web player at http://music.xbox.com or through the Xbox Music app on all Windows 8 tablets and PCs. Discovering and enjoying free music is as easy as typing an artist or song name and hitting “play.” Songs are instantly available to stream at no cost and for you to create an unlimited amount of playlists.

Xbox Music will continue to grow and evolve over the coming months. Microsoft will add Radio to the free Web player, a quick and dynamic way to personalize your collection, discover new favorites, and create ultimate playlists by launching instant mixes based on your favorite artists. With unlimited skips and a view of the full recommended music stream, Radio puts you in control of your Internet radio experience.

Xbox Music will grow on Windows 8 when it adds the anticipated new Web Playlist tool this fall. The tool scans all the artists and music available on a given Web page and creates a custom playlist of all that music.
