LOCKER LOAD USING A ZIP FILE
After an MP3 album purchase, a zip file containing all the user's purchased tracks is available for the user to download at https://store.example.com/download/A32X5yz.zip (this is just a random zip file name). The locker load process is initiated with this URL as the target file to load. The locker load process will unpack the zip file, load the tracks into the user's locker and create a playlist for the tracks loaded.
It is assumed that all the tracks in the file are either non-DRM music files or album art images. Files with extension jpg, jpeg, or png will be detected as album art images. For the purposes of album art, it is necessary that all files in the zip file be from the same album. All image files detected will be stored as album art images for that album. To handle the case where a locker load contains tracks from multiple albums and album art is available, it is recommended that the tracks be locker loaded via m3u playlist rather than zip file. See below for more info. In the case where tracks in the zip file are not all from the same album, images will be ignored.
