The mobile music war just hit a higher note.
Google on Friday launched its long-awaited Google Play Music application for Apple's iOS. The free application, which is available now in the Apple App Store, allows users to stream millions of songs and create custom radio stations. Unlike Apple's iTunes Radio and Pandora, there are no skip limits on Google Music.
Those who want to listen to their own libraries also can upload up to 20,000 of their own songs to Google's music cloud service and access those on other devices.
