ok, so i tried to add a song to my memory card through bluetooth yesterday and it failed after it was about half way through.
i still tried to play the song on my phone, and it was fine until it was about half way through, until it cut to another song.

this song i had deleted from my memory card months earlier, and isnt stored on my new laptop, or any other storage medium, so why is it appearing for no reason? do songs actually get deleted or just float around on the memory card?
