Wow. I just have read that Spotify has started to port their libspotify and a player over to AmigaOS 4.x. It seems they got a SAM 460 with AmigaOS4 and the SDK installed by a (indeed very cool) donator and agreed to port their software. You can already get a view on the machine it is developed on in the appropriate news over at Gizmodo FR. More information can be found in the appropriate thread over at amigans.net. Greatness! Well done!
