With a good headphone, and I recommend the Koss Sportapro, you can experience one of the most powerful forces in the universe - rock music! It is potent with some practical applications that make life much more pleasurable. As an example, while doing chores you would rather not listening to rock music with good headphones makes it seem almost enjoyable. In fact sometimes I am disappointed the chores are all done! I also believe you can use rock music to channel from the infinite intelligence, the place where all knowledge is stored. You can literally can make fantastic discoveries, and more! It's a mental state created by the music. High vibrations allow it to flow. There's lots of rock music to listen to. The meat of it is from about 1971 to 1991, but you can find excellent songs years before and after. If I had to recommend one for you to try it would be "Barracuda" by Heart. The studio version only! Wow!
