I didn’t do it. When I got to the recommended site for a pre-paid online card, I realized I’d have to provide bank info to yet another online site. I’m trying very hard not to do that. If there’s a particular performance you’re looking for, try a search engine, using composer, performer, and date. I often find Yandex is more useful than Google/Bing/Yahoo in finding videos of classical music. People post classical performance videos on VK and on disk space that comes with Yandex mail & VK mail. Western DRM doesn’t get checked as often there.
