How do I open the music on my iPad?

Most of our music files are delivered as ZIP files. These files are supported by iPads out of the box.

1. Download the file(s) from the download page after purchase

2. Open the Files app, then find the ZIP file(s) you downloaded

3. A folder is created containing the files. To change its name, touch and hold on the folder, then tap Rename.
