The process involved in downloading music to your phone depends primarily on the type of phone you have and the service used to download music. Google Play, for instance, provides a mobile app that allows you to download subscription albums, radio stations and playlists.
Other music services may provide their own mobile apps for music downloads. Cell phone owners should check with their specific app stores to find available apps. Some websites allow phone owners to download music directly from the Internet to a mobile device, although the legality of these may be questionable. Many legal music services require a monthly subscription fee.
