Bug 479592

SUMMARY
In the track view, if I touch (on mobile) a song, I would expect it to play just that one song. (Whether it enqueues it or replaces the playlist with it is up for debate, and IMHO it should be configurable.) Unfortunately, what the touch does instead is that it replaces the playlist with the entire contents of the track view! If I have not done a search, this means it adds every single song in my collection to the playlist! Obviously, this is NOT what I want.

Enqueuing the whole album MIGHT make sense for the album view, but for the track view, the touch should really only add that one track.

STEPS TO REPRODUCE
1. Start Elisa on Plasma Mobile (though the behavior is probably the same on desktop).
2. Open the Tracks view if not already opened.
3. Touch / click on a track.

OBSERVED RESULT
The entire contents of the Track view are added to the playlist, replacing its existing contents. If I have not done a search, this means it adds every single song in my collection to the playlist! (And it does not even jump to that song in the playlist, but just starts from the top, which is probably a bug, but it would not happen if it were not behaving that weirdly in the first place.) Even when I do a search, I am going to stop typing once I see the song I am looking for and do not want to enqueue any other songs that happen to match the substring I am searching for.

EXPECTED RESULT
The one song that I touched / clicked on (and only that one song!) is added to the playlist. Either it replaces the existing playlist contents, or it is appended to it, the other option should be available from the "..." menu. But in no event should it add the entire contents of the Tracks view.

The workaround is to use the … button and the enqueue option. But that popup is missing a replace / play now option, so if I want that, I have to first empty the playlist, then use "Add to queue", and then play. So I have to do 6 touches (open the playlist, empty it, close it, open the … menu, enqueue, play) instead of the 1 I am used to, or at least only 2 as I suggest (open the … menu, "Replace playlist and play now"). I hope you agree that this is a usability regression.
