Playing music on phone, and at the next song no sound?

well, this could happen because of.... your phone is still connected through USB. well it happened to mine, so i wanted to post it just in case.

my phone was connected to the usb cable, for transferring files at that time. so what happened was, suddenly, i noticed the next track seems quiet. so i checked my phone, well its playing... hmm.. then i adjusted the volume up and down, and it started coming out with the sound. then i thought hmm.... then the next song, it happened again, it went quiet. and so i adjusted the volume again, and again, the sound came back. so then i pulled out the usb cable and tried again... and WALA, it played normally now...

i tested it again, by connecting the USB cable back to the phone, and the same problem occurs, so i guess its the USB cable causing the problem... so go figure ^_^
