Google introduced today a new “cloud” entertainment service, dubbed Google Play, that will allow users to access their music, movies, books and apps on the web and across Android phones and devices.

The tech giant is also folding its current stand-alone offerings for music, books and apps into the Google Play service.

“Starting today, Android Market, Google Music and the Google eBookstore will become part of Google Play,” the company said in a statement.

The Google Play service can be accessed through the Google toolbar as well as at http://www.play.google.com website.

For the next seven days, Google also plans to promote the service by offering products at a steep discount of 25 cents, including the album “Now That’s What I Call Music 41,” the indie movie, “Puncture” and the book “Extremely Loud and Incredibly Close.”

Separately, the company said that Google Music has hit about four million subscribers. The streaming music service, which doesn’t have permission to offer songs from Warner Music Group, launched last November with one million users.

Some reports have suggested that Google Music had struggled to keep hold of its subscribers.
