When I plug in my iPod after listening to it, it scrobbles all the tracks in a collective, so it'll scrobble each time a song was played, and it groups them together.
So it might show one song six times in a row, and that's because I listened to that song six times since last plugging in my iPod, but not necessarily in a row.
Cleared my scrobble history today. It saved my loved tracks so that's fine with me. It was super skewed by the imported scrobbles from my iTunes and it was bugging me.
