If you want to stream electronic music, Digitally Imported (di.fm) is one of the best sources you can turn to. The service's Android app, Digitally Imported Radio also does it justice on mobile thanks to wide channel support, a great and updated interface, and frequent changes to implement new features like casting support. The app, however, lacked one option when it was redesigned in June of last year: landscape support. That's finally being implemented along with interface optimizations for tablets.
Version 3.1 of the app adds "first class support for Android tablets," and restores support for landscape orientation on phones. I'm not sure about the expletives there, but the interface definitely looks nice on tablets, split into two panes and making better use of space in both portrait and landscape orientations on larger screens. You can see it in the screenshots below.
If you've never installed Digitally Imported on your phone or tablet, you can grab it from this widget and start enjoying all the Trance, House, EDM, Dance, and other electronic music genres that you love.
