Someone bought a Coby MP3 Player for their daughter. They were told it can hold approx. 40 songs. They can only get about 7 on it. The software that came with the Coby is just to configure it, via, USB port, to a computer, to download songs to it. Is there any software that is compatible with "compressing' or changing the format so more songs can fit on the Coby MP3 Player?
