I was the queen of flash cards, heck I still have a loooooooot of mine. If I couldn't put it on a card I would make up silly sayings to remember long lists of information(thank you science classes). If I couldn't do either I would set myself down and reread the information until it felt like it was spilling out of my ears. And I used to do it all with music on, so it's not like you can't have sound in the background. As you've found out it can help you focus even better. AND it's been proven that if you listen to that same song while applying the information you'll remember it better! Obviously you can't take music into tests, but you can hum it or recite some of the lyrics to yourself and it really does help.
