Kizashi Club

I seldom hook up my phone to the USB port, but I was going out and being in the car a long time, so I plugged it in. I then noticed that the USB light just kept on flashing. I don't remember it doing that before. I thought it just stayed on till unplugged. It did continue to recharge my phone though. So, does anyone know if there is a problem here?

I believe it means it cannot recognize the music files.

That makes sense as my phone (Samsung G2) said it does not support it if I tried to play tunes. But I could have sworn it didn't do that before...
