Find out why you love your iPod so much.

You know how playing your favorite CD can make you happy? We'll, scientists have discovered that listening to different types of music -- even certain tunes -- can help your body and mind in specific ways. Find out how music helps you.

Concentrate: Solving a jigsaw puzzle? Moving a couch? Play Mozart. Researchers say classical music improves spatial thinking. It's not that pianos and violins make you smarter per se, but they create new pathways in the brain and boosting your problem-solving skills, thanks to the complex musical structure. Also, powerful chords trigger brainwaves that jive in sync, so if you listen to faster beats you'll be more alert and focused.

Relax: It's a fact: Playing a Norah Jones CD will make you Zen. That's because the chords in soft rock create changes in brainwaves that control breathing and heart rate. In other words, playing a soothing soft rock CD will calm you down, counteracting and even preventing the damaging effects of chronic stress. Ah....

Exercise: You know how blasting the latest Shakira song gives you a jolt at the gym? Well there's a good reason for that. Studies show listening to tunes during your workout helps people exercise harder, and longer, and even distracts them from fatigue. And English researchers found certain tempos (120-140 beats per minute) correspond to a person's heart rate during exercise -- say, during 20 minutes on the elliptical. Lead authors say "Push It" by Salt-N-Pepa, "Drop It Like It's Hot" by Snoop Dogg, and the dance remix of "Umbrella" by Rihanna does the trick.

Your unborn baby's memory: Surprisingly, fetuses can clearly hear at 20 weeks of pregnancy and even remember the tunes up to their first year of life, especially if you play the same song every day during the last three months of pregnancy. According to Dr. Alexandra Lamont, a lecturer in the psychology of music at Keele University: "It used to be assumed that it was really noisy in the womb but actually it's quite quiet." Any type of music will do, so take your pick!

Enjoy girl's night out: If you tend to down martinis quickly around your pals, that's no coincidence. According to a new French study, loud music leads to more drinking in less time. Study authors surmise that high sound levels cause excitement, which leads to people drinking faster and ordering more cocktails. Another reason to speed drink: Bars often blast music at deafening levels so patrons imbibe more when they can't hear those around them.
