When I try downloading an mp3 into my playlist, it shows up in the folder while I have my phone connected to my computer, but as soon as I disconnect, then go to the folder on the phone, nothing is there. When I connect the phone to the computer again, it shows all the mp3's I thought I downloaded. And just FYI, it worked perfectly until today! I shut it down, took the battery out, and started it back up again... same thing. Any ideas as to why it's suddenly doing this?
