Hey! Yes, the site is creating a paywall for you file, so it's not a place where the customer can preview. It's more like selling a cd. They can't listen to it on the direct current site, but when they buy it, they have the file forever and can listen to it offline. On your dashboard, you can find both an embed link that you can put on your website and a standalone link (click preview) for each product. You can sell individual tracks or a whole album (although you'd need to zip it into one file).

Here's a sample website that I built with a direct current embed in it:

https://two-little-tracks.vercel.app/

Here's the standalone link to the "album" (it's just two old tracks I had never used):

https://directcurrent.space/checkout/two-little-tracks

Before sharing, double check that you've got your full NWC string in there and that it's a read-only string. You should be able to click through and see a QR at the checkout on your preview page. That's exactly how your customers can pay for a track or an album.
