How do you play a track once and the stop

For a playlist, near as I can tell, just starting a playlist by tapping its thumbnail will play all its songs and then stop. I just tried it and kept tapping forward to cycle through all its songs, and after the last song finished, it stopped. I have Repeat turned off as well.

For a single song though, that's a tough one. Everything I tried always triggered Up Next with additional songs. And the songs that it included in Up Next seems to be context sensitive:

- If you're viewing Songs, and play a song, Up Next will fill up with 20 randomly selected songs from your entire music library (and then continue to select songs from your entire music library).

- If you're viewing Artists, and drill down into an album, and then play a song, Up Next will fill up with up to 20 randomly selected songs from that same album, and then continue to select remaining songs from that album until all are played and then stop.

+ If that album only has one song, it will play that song and then stop.

- Same for viewing by Albums, Genres, Composers, etc...

- If you're viewing Playlists, and drill down into a playlist, and then play a song, Up Next will fill up with up to 20 randomly selected songs from that same playlist, and then continue to select remaining songs from that playlist until all are played and then stop.

+ If that playlist only has one song, it will play that song and then stop.

+ So you could create a new playlist, add the song to that playlist, and then play either that song from the playlist or the playlist itself, and it'll play the one song and stop. But who wants to do that?

Given Apple's insistence on starting Up Next everytime, i then tried triggering the playing of songs through other means than the Music app:

- Telling Siri to play a song, starts that song, but then Up Next will fill up with songs from that same album.

+ So it works the same as above (i.e. if that album only has one song, it will play it and stop).

- Seems silly to say, but maybe a third-party app provides the ability to play just a single song once and then stop. I'm not aware of any, but that's only because I just use to default Music app.

Ultimately, I did find a way to play a single song, and only that song and then stop, using only the functionality included in a stock iPhone, but you're probably not going to like it.

The answer is Search. Bring up the search screen, search for your song, and assuming it appears under the "MY MUSIC" section, tap the play button on the right side of the screen, and it will play that song, only that song, and then stop.

It only shows 3 matches, however. You can tap "Show More", but even then it only shows 6 matches. If the song still isn't in those first 6 matches it finds, you'll have to get creative with your search terms to narrow down the matches until the one you want appears.

Not a great solution, I'm afraid, but it meets the criteria.

Edit: Sorry, I just noticed you mentioned iPad and iOS 8. These details are for iPhone and iOS 9, but I think they might still apply.
