When using a Music Box Widget, the Artist's name does not show up when using it with Napster. It does work with other players like the Samsung Music Player app, though. It did work with Napster in the past. I hope it can be fixed. I added 2 images to show what I mean. One shows the widget with Napster and the other one with the Music Player by Samsung.
Hi, i tested Napster today and i can confirm the issue, this is a Player issue, Napster is not sending data to the Android Media subsystem, you will probably experience this issue with any third party app that tries to read his data. i also checked if they provide any "custom" API to read infos but didnt find any. My suggestion is to report this to the Napster player devs and see if that can be fixed.
