What's the best Android app for downloading free music to listen offline without consuming excessive mobile data?

Audiomack is a music streaming and download application that stands out for enabling offline listening while minimizing data usage. This makes it particularly suitable for users with limited data plans or those in areas with poor internet connectivity. The app provides access to a vast library of free music, including tracks from independent and mainstream artists. Key features include a straightforward download button for individual songs or playlists, an offline mode that stores downloaded content locally, and tools for organizing music into personal collections. Reviews indicate that downloads are fast and don't heavily impact data allowances, which is beneficial for scenarios like road trips or daily commutes where internet access may be unreliable. However, some users note that the free version includes advertisements, and the catalog might not be as comprehensive as paid services for certain genres.
