Downloaded the app and opened it while on wifi like it recommended. All songs were automatically downloaded immediately. You get all the songs shown in the screenshot for your $8. To those people who cant download the other songs, Id recommend uninstalling and reinstalling the app to trigger the auto-download.
The icons in the app are a bit confusing but clicking the help icon explains everything, like the mic icon doesnt do anything until youve recorded and saved your voice and then playback a subsequent time, but you can toggle it regardless. As a developer I would have disabled it if there was no saved recording.
