The easiest way to describe this is to say I "had" tunes on my laptop which I transfered from my W7 via a USB flashdrive. The folder & tunes have long since been deleted & recycling bin emptied & the Vista has been defragged at least twice, yet when I recently installed iTunes to transfer contents from one iPhone to the other one, the tunes I "had" on here, mysteriously showed up in iTunes. How ?? NO, I never had the tunes on the iPhone. Its a mystery to me but I bet sonmeone here has an answer.
