I really like

Whatever it is that Spinner uses to embed music into their posts. It's simple to use, never needs annoying load time, and they use it really well (they almost always include whatever song(s) a post is talking about in the post). A lot of sites get it wrong or only half right, but I like what Spinner's working with. For example, this post about Kimya Dawson & Juno's music. Their photo slideshows are also equally fast-to-load and easy to navigate. Just thought I'd share.
