I like trance, though I can't say I'm an expert on it. I had friends back in high school who were more knowledgeable. They would frequent the World Electronic Music Festival, which was held yearly near where I live. Unfortunately, from what they told me, that event had copious amounts of drugs, alcohol, and milfs, so I never attended. Here is a link one of them gave me that gives you samples of different types of electronic music.
