As many of you noted, iTunes originally only posted "The Daydream" as a single; "The Disconnect" was supposed to be included as the B-side. The error has been fixed; the single now shows up as a new item with both songs included. Unfortunately it is now missing all the original comments and ratings. At any rate you can now get the full version of the single here.
Others have asked whether there is currently any alternative to iTunes for purchasing the songs. Ghostly released the single as a 2 month exclusive on iTunes, so when that time is up it will be available everywhere, including right here for direct purchase.
