I might take a guess at what's occurring. In my experience if I put my phone down at a certain spot on a table the volume is *heavily* muted. Perhaps the first song that was played was sufficiently loud enough that you could tell it was playing with the phone still on the table and perhaps the second song was quiet enough that you didn't notice that it was playing until you simultaneously picked up the phone and hit the power button?
tl;dr: it was colonel mustard in the library with the candlestick
