* “Apple Music,” as it appears in Comscore’s monthly reporting since July, is the same measured entity as the previously named “iTunes Radio/iCloud” that has been reported in past months’ mobile rankings. This entity, now under the new name, is referring to Apple’s native music app, which captures all music activity within that app, including listening via the streaming service, radio service and users’ personally downloaded music libraries.
