Audio Hijack Pro & Spotify -- No Polling
-- Usage
-- 1. Edit the settings (see below). This step is NECESSARY the first time you use it!
-- 2. Run this script (this should open Audio Hijack Pro and Spotify)
--
-- NOTE: the script assumes that each track is played entirely. You CANNOT skip tracks in Spotify.
-- If you do so the script will get out of sync and the resulting files contain partial or multiple songs.
-- You can abort a recordig session by stopping this script and ending (manually) the recording
-- in Audio Hijack Pro.
--
-- You need to have "atomicparsley" installed on your system. You can install the application with
-- homebrew using "brew install atomicparsley" (see http://brew.sh/)
--
-- The recording settings for Audio Hijack Pro NEED to be defined here, they CANNOT be changed
-- withing the application itself.
-- Every time the script is executed, the settings defined here are applied to Audio Hijack Pro,
-- customizations in the application are overwritten.

had more issues with blobs of audio at the very end. now everything seems to be fine. applescript->spotify seems to have a little lag before commands are performed.

this needs some cleanup... but it's recording beautiful now.
