good music machine vs Auranova

good music machine is made for people who love a well organized library and wish the column browser was available on iOS. - Play music in your local or cloud library
- Play mp3 or m4a files in a local or iCloud drive folder
- A folder of files uses the files’ metadata to build your library.
- iCloud files can be downloaded to your device for offline play. - Supports CarPlay - Uses logical columns (genre, album, artist) for finding your music - You can search any of the lists - You can turn off the genre column - Optionally you can filter using an additional composer column for classical music (or any genre you prefer) - You can browse your albums by album art or just text If you have questions, comments, feedback or found a bug, feel free to contact me! Note: good music machine is not entirely free. 
The first 25 artists for both the music library or a folder of files are free.
