It depends. I would like to have said "no", but given the prices I have paid over the years for e.g. the five Game Music Concerts, Turrican Soundtrack Anthology or some other Kickstarter projects, I suspect that I might pay it. It would have to be an item that I want for its music, probably with a significant nostalgic value, and likely it would have to be exclusive in some way (not "pay now and later we will make it available on Bandcamp"). I would be sorely tempted if, for example, the soundtrack to Monkey Island 2 was recorded with a live orchestra and released on CD, or if some of my favorite ZX Spectrum tunes got released in some upgraded form (I was lucky that Allister Brimble accepted some of my suggestions for
ZX Spectrum: A Visual Compendium's companion CD before the Kickstarter campaign even started, so I hadn't had to pay quite that much as 1000 euro. But it's a distinct possibility that I would, if I had to.)
