spotifyimport is a command line program to import songs into Spotify from
your Apple Music library.
Songs will added to "Liked Songs" in Spotify. The program reads Apple Music library data from scrobble.growl.space API response JSON, which should be fed into stdin.
Run with the --help flag to print help information.
By default, the program runs in "dry run" mode (it doesn't actually add songs
to Spotify, but just prints what it would do). Use the --mutate flag to
actually add songs.
The list of songs that fail to be added, if any, will be written to
failures_<timestamp>.json.
