I'm actually working on a service which sits on top of SoundCloud. It's still in its infancy, but I'd love to hear what people think of the concept; the service aims to help musicians and photographers expose their content to a wider audience, and on the flip side, allows you to sit back and listen to a playlist of music whilst enjoying a beautiful photo slide show. The playlists are tailored to a user's mood, and you're able to filter the music based on genre. The website's voliyo.com, and if anyone's interested in signing up to the beta as a photographer or musician, feel free to message me for an invite code!
