Along with a large music library, Spotify supports an offline mode. To use this feature, you must subscribe to Spotify Premium. This subscription gives you music caching on a desktop or mobile device so that you can listen to tracks without connecting to the internet. With Plus, the app automatically downloads your favorite stations to your mobile device and switches to one of those stations if you lose your internet connection. With Pandora Premium, you get the same feature and the added capability to download any album, song, or playlist in Pandora’s vast library to play offline. SoundCloud offline access works on both the SoundCloud Go and Go+ membership. However, some songs on SoundCloud are free to download without a paid subscription. The YouTube Music app can be used to save music to a smartphone or tablet, so you can stream your library without being connected to the service. However, a YouTube Premium subscription is needed to take advantage of this feature. To avoid using cellular data, download songs to your phone from Apple Music while you have a Wi-Fi connection. You can create and download playlists or try one of the curated playlists Apple Music offers. Apple Music requires a subscription, but you can try it free for three months. A feature called Mobile Station Caching, which is available for the Plus and Premium subscription packages, stores the contents of particular stations on your mobile devices so that you can listen to those stations without a network connection. If you want more flexibility, the Premium package allows you to cache individual songs and playlists for offline listening rather than only the contents of stations. Deezer offers a 30-day free trial of its service. A subscription also removes ads.
