Yeah, as I mentioned earlier in the thread, memories are extremely inaccurate. When it comes down to it, they are merely very poor records of an imperfect reconstruction of incomplete sensory input. Not only are they subjective, and not only do they change every time you access them, as Mr Awe said, but they can be easily made up out of whole cloth, and there is absolutely no way to distinguish between a true memory and an artificial memory for either the subject or the neurologist (both function the exact same way physically in the brain). Another very interesting memory phenomenon is stolen memories. They happen most often between siblings, and I actually experienced this once -- I stole a memory from my sister. As for music, there's been some really fascinating research into the unique nature of music in human brains. I think sometimes people are in awe of how powerful music is at triggering memories, or as a nemonic (everyone can remember song lyrics to hundreds, if not thousands of songs, but would be hard-pressed to memorize the same amount of text from a novel), but I think sometimes people don't realize is that music is a form of language, just a different form. The unique thing about human language (at least as is known thus far) is its musicality. Lots of species have words -- for specific things, actions, events, etc., indeed, many higher-order primates have speech like this, and dolphins too. Birds have music, and it is definitely used as a form of language, with different songs communicating different things. But humans are the only species that have both. We have words for things but also tonality, and that separates our language from other animals, and could be why our language is so much more advanced. Some have even postulated that early humans sang to each other before they spoke, which is a hypothesis I absolutely love, because it is excellent picturing caveman opera. For me, music is a very important part of my life, since I was a musician from a young age, and I can read music. It brings back very powerful memories from childhood, and very strong feelings. However, my earliest memories are completely silent, because I was deaf until age 4.
