Album artwork changes?

The artwork on my iPhone seems to change from the artwork I have chosen in my iTunes library, so it is artwork from a different album to the album that is in the songs info. For example, the artwork on my computer is the artwork from the single, however the artwork on my iPhone is from a compilation album. And it has done this with many songs. I would like if there is any possible way to turn it off.

My iTunes and iPhone are both up to date.
