The rest of the app is dedicated to content, with tracks and playlists presented in large 1x1 squares just like iTunes. It uses a suave dark theme with a sidebar for navigation and media controls along the bottom of the window. On first glance you'd be forgiven for mistaking Soundnode for an official app. The player is available for macOS as well as Windows and Linux, which might explain why it feels a little more developed than some of the other apps on this list.
Far from a website running in a frame, Soundnode is a completely native and open source SoundCloud app.
