It seems while playing the same song, the play count is not increased. Normally it is an intended behavior, but it would be better if the app provides an option to increase play count even if repeating only one song.
An option to increase play counts on the same song, repeat-one-song mode or repeat mode with one song in a queue.
I like to listen to the same song but so far it’s hard to calculate how many times I listened to that song. This feature will help a lot. Furthermore, it won’t bother others who still satisfied with current app since it is an “option”.
