Pay what you want for this amazing soundtrack - Kotaku - "Composed by Jake 'Virt' Kaufman along with contributions from Mega Man composer Manami Matsumae, the Shovel Knight OST is a collection of anthemic chiptune compositions that, like the game it's attached to, both recalls the classic games of the past and leaves its own imprint."
The game is not released in Europe yet but I can't wait, especially after the stellar reviews it's gotten so far. I think you can pick it up for the PC though - Wii U and 3DS releases were slightly delayed.
Marketing blurb from the site:
Immediate download of 48-track album in the high-quality format of your choice (MP3, FLAC, and more). Paying supporters also get unlimited streaming via the free Bandcamp app.
The NES compiled version of this soundtrack (a single file under a megabyte, which contains the machine-language code for the music, and can be played back directly on real NES / Famicom hardware, using special hobbyist flash cartridges -- or listened to in dozens of free NSF players available on every imaginable computer OS or phone -- can be found here:http://biglionmusic.com/Shovel_Knight_Music.nsf
The only NSF player it has been currently tested in (as of release day, 6/26/2014) are VirtuaNSF and NotSoFatso, both freely available, with lots of cool features for study and examination. More players will be tested, and a hardware recording is planned soon!
