Google unveiled its much-anticipated digital music store today, opening a new front in its battle with Apple to provide services over mobile devices. For the first time, Google will sell songs on the Android Market, its online store for apps, movies, and books. Some songs are free, while others were priced at 69 cents, 99 cents, and $1.29—the same prices as on Apple's iTunes.
Once someone buys a song, it can be downloaded and is automatically uploaded for free into an online locker. The song can then be streamed over computer and mobile phone browsers, including the Safari browser, which comes on Apple devices such as the iPad.
