I've been using an iphone for a month now and have just ran into a strange problem.

I can still create playlists on my iphone but for some strange reason the phone will not automatically change songs any more. In other words: if i use the button on my headphones (double-click) or touch "next song"-button on the screen, the phone will start playing the next song but it will not start playing the next song automatically once it finishes with a song (which is the whole idea of having the playlist in the first place). So, without manually changing songs it will play one song over and over again.

Everything worked fine till today, so, I am wondering what has gone wrong. Is there any way to fix it? Do I have to restore the phone using iTunes?

UPDATE! Problem solved... my mistake i guess i had accidentally turned on the "repeat" - option
