LG :: Vx8560 Mp3s On Both Internal And External Memory?

How can you put mp3s on both internal and external memory on the VX8560 (Chocolate 3)? I filled up a 8gb card, and everything works fine with no mp3s on internal memory. When I drop mp3s in the internal memory Mymusic folder using bitpim, the phone suddenly ignores all of the mp3s on the card, and only shows the ones in internal memory. I've had horrible luck with using the Vcast software, so I'm hoping that's not the answer. I also tried transfering from the card to internal mem using the phone, but during the transfer the phone said the songs had illegal titles (I'm guessing because I have very long file names - because I put artist, album, song all in the title). Then it showed that none of them transfered over. Anyhow - any help much appreciated.

This is my actually my second VX8560 - lost one a month ago on a mountain bike ride, and decided to just get the same phone instead of something different because this one is perfect for me (a lot to do with the phones small size).
