@Gargron I'm kind of divided. I've found so much music on #spotify that was either never released on CD or was hard to find. That music was essentially gone before streaming.
A band I love released a special limited edition CD three years ago with a lot of never released material. The CD is now $200 + on eBay when available. It's not on streaming, so it might as well be unavailable.
TV and movies though, that is a business model that is broken on streaming.
