By default, up to eight of your most recent releases will appear beneath your stream, allowing fans to purchase releases without interrupting their view of the show. You can choose specific releases and re-order them in the editor.
Do not underestimate the value of having a merch table integrated with your live stream. It’s an opportunity for fans to show their support (and every time they do, a notification of a sale will appear in the live chat). You could consider releasing merch just ahead of the show, adding signed copies of existing merch or whatever else you can think of.
You also have the option of bundling a digital release with the purchase of a live stream ticket. For instance, you could stream an album launch party and include the album in the ticket price.
