Why is my iphone 4 on shuffle?

I have the iPhone 4 and my music will not play normally it is always on shuffle and i don't know how to stop it. Any way i can fix this?

Start playing your music, and when it gets to the screen (like after you pick the song in the list), make sure you have the timer on there, (the grey/see throughish bar). If it's not there, or you don't know what it is, tap the screen somewhere on the album art and see how the screen changes. Once you get the bar to show up, on the bottom right of that bar (not the whole screen) there's two arrows criss crossing. If it's colored (like orange or blue or whatever) then it's on shuffle. Hit that until it's not colored anymore.

TL;DR:
1. Get to the screen with the play/pause options
2. Tap the screen once to get a grey see throughish bar (you might already have it up)
3.In the lower right corner (not of the screen), there should be two arrows criss-crossing. Hit that and shuffle should turn off.
