When I double-click an MP3 file to open it by Groove Music, it will stay in "Albums" with the prompts: "We didn't find any music on this PC".
But I hope: when it cannot determine the album, should can automatically go to "Now playing" screen page, rather than have to click "Now playing" to go to it.
In addition, till present, playing a same audio file, Groove Music vs. Windows Media Player, Groove Music's sound quality (or playing effect) is still slightly inferior.
I hope that Microsoft could improve this app to solve the problem in the future. Thanks.
