Apple Music is live as iOS 8.4 gets pushed out
The on-demand streaming service gives subscribers the opportunity to select tunes from a library of 30 million songs. While there is no ad-supported free version of that service, those with an Apple ID can listen to Beats 1 for free, listen for free to other Apple radio stations with limited skips, and access Connects without a charge. The latter is a social-media "bulletin board" where artists can connect and socialize with their fans.
The iOS 8.4 update is being sent out OTA, and is also available through iTunes.
