I went for a run on Saturday with all my music. Woke up today, nothing. The SD card is empty and there's only 5 songs on my phone! That's 50 songs lost and I don't even have a computer to use to put them back on. My computer died a few weeks ago, and I don't have any other. Now what? I've restarted, took out and replaced the battery and SD card. Nothing. Considering I definitely didn't do it, this is awful.
