Music Streaming Wars: Top 8 Contenders

Google Music Play All Access

Background: Unveiled during its developer conference, Google's service is mostly notable for beating Apple to the punch.

Specs: $9.99 per month for streaming access to "millions" of songs, plus a radio service in the same vein as Pandora, which allows unlimited skips.

Is it working? So far, it's received favorable reviews, but it's early yet. The service arrives on iOS soon, and though the Web app isn't quite as elegant as anything Apple has done, it's got enough features to keep users interested.
