Sound Sync is a Node script which downloads your liked tracks on SoundCloud and uploads them to Amazon S3.
This utility can be used to sync your SoundCloud tracks to Amazon S3. After wards, you can run the included AppleScript to sync the songs with iTunes.
osascript scripts/sync_songs.scpt
The included sync_songs.sh script is one that I use personally which will send stdout and stderr to CloudWatch. Note that you will need the cw-pipe global npm module.
