Music and audio apps are mobile and web-based applications that allow users to listen to, discover, and manage music and audio content on their devices. These apps can be used to stream music from online services, such as Spotify, Apple Music, and Tidal, or to play music stored on the device. Some popular examples of music and audio apps include Spotify, Pandora, Soundcloud, and Shazam. These apps offer features like creating playlists, discovering new music, and listening to podcasts. Some music apps also provide additional features like lyrics, offline listening, and integration with smart home devices, allowing users to control music playback through voice commands.
