Bandcamp's streaming product and tech is a little better than y'all gave them credit for. They offer a streaming app that let's you stream from your purchased library, which works well.
It will never happen, but I can dream about what integration could be like. I would love to be able to have my purchases inform say, a car radio in Fortnite. This was my favorite Forza feature back when it worked with whatver the hell Microsoft's Music Streaming product was.
After the Amazon \ Comixology debacle last month, little to no hope for intergrations going well.
