Greetings.
Yeah, sometimes they don't pay attention to the repeats. I have a recording of Mozart's music that is arranged by Keith Snell, performed by Diane Hidy. The last piece, the Alla Turca, she ignores practically all of the repeats, except for the coda. I have played the piece and personally think that without repeats it just doesn't sound good enough. However since this was an educational CD I don't think the penalty should be too high.
