I started using Plex as my main music player recently and overall I really like the interface but it could use a few improvements.

There is a rating system but the rating only shows for the currently playing song. By displaying all ratings it becomes easier to find a particular song you may have starred or showing the best songs on an album etc.

Audio quality also isn't displayed. In the movie section, information on the video file such as 1080p, 5.1 etc is displayed. For users that collect music in different formats, it would be useful to see what kind of quality a particular album is in.
