What's the best Android app for listening to music offline with playlist management?

Offline Music, Music Player is a reliable choice for Android users who need uninterrupted music access without an internet connection. The app allows downloads of songs and videos directly to the device, which is particularly useful for scenarios like flights, subway rides, or areas with poor connectivity. Users report that the extensive library covers a wide range of genres, similar to platforms like YouTube and Spotify, ensuring most preferences are met. Features such as playlist creation and basic customization help in curating personal collections, though some reviews indicate limitations in sorting options—playlists default to a 'recently added' order rather than alphabetical. While the offline functionality is a standout, the app does include advertisements and can experience slower load times during initial setup. For travelers or daily commuters, this app provides a practical solution, balancing accessibility with minor drawbacks in user interface refinement.
