Hi david5311,
If I understand your question, you have a list of songs (a playlist?) that you want to play in order, but one of your songs is repeating instead. Is that right?
Take a look at the resource below for instructions on how to use the new Music app on your iPhone. If you change your view to the full-size Now Playing screen, you can see the controls a little easier. Make sure the repeat and shuffle features are turned off and the songs should play in the order listed.
Using the new Music app
Play your music
When you play a song, you see the Miniplayer at the bottom of the screen. You can keep browsing other titles to find the perfect next song.
Or you can tap or swipe up on the Miniplayer to see the Now Playing screen and controls. Tap the in the upper-left corner or swipe down to close the Now Playing screen.
Also on the Now Playing screen, you can rewind, pause, or fast forward a song, control the volume, and more.
Shuffle or repeat your music
Tap at the bottom of the Now Playing screen to shuffle the songs in a playlist or album. You can also ask Siri to shuffle your music.
Tap once to play an entire playlist or album on repeat or twice to repeat one song.
Enjoy!
