How to turn off the shuffle feature on my iPhone iPod?

No matter what I do, I can no longer skip to the following track. This happens when I tap the Skip button (>>|) and also when I double-click the clicker on my headset. I've rebooted and fiddled with the shuffle button on the top of the playlists. Tapping that button does exactly the same thing as clicking the skip button (>>|). Any ideas?

I've had the same problem for a while now and I finally found the answer. When you open an artist, album, playlist, etc. And you click a song and it begins playing, click the album art once and a little drop down time line and shuffle, repeat options appear. If your shuffle symbol is blue then shuffle is on. Just click it once to turn it off. (shuffle is to the right, repeat to the left
