If you pay for it, are you getting a physical copy or is it meant as a donation? :S
I do not believe you’ll get a physical copy.
You can buy the soundtrack on iTunes or download it for free (I believe).
You can donate to Joel to support him.
I hope this answers all of your questions.
The donation is separate.
You can download the soundtrack for free. There is no physical copy.
You could make a physical copy though, by printing the cover image, putting it in a jewel case, and burning the music to a disk.
If you really wanted to, anyway
second that AND cassette…AND vinyl.
Question solved.
