I use my ipod quite a bit during the day and the management of the individual files is somewhat of a hazzle. Does anyone have experience with software (free or commercial) that merges multiple mp3 into one large mp3 file? Allowing me to have one file per CD for instance I've found a one product (ezsoftmagic) that appears to work, but I'm not familiar with the company. Any help or pointers would be much appreciated.
