Oh heck yeah. Simply put anything that improves your brain’s ability to function will improve anything you do. I have to disagree with scientists saying that our brain is an involuntary organ like the heart or stomach. We control and use our brain to do everything. Meditation is probably not the best thing to do before a test, the point of meditation is to clear the mind so you can more easily learn some new. Music in a sense stimulates brain activity, the brain actually works a lot more than we know when we listen to music. Especially Classical because classical music takes a lot of attention to follow. Pop music is very simple and not hard to make sense of, classical music is highly advanced in it’s structure so the brain will work twice as much to comprehend it.
