The OSCAR MP3 player is operated according to a new, intuitive concept which is vastly different from anything you’ve seen on conventional audio equipment.Although there are no hard and fast ‘rules’ for the format of a CD or hard disk when it comes to song titles and the order in which they are stored, it is useful and convenient to arrange for an MP3 CD or a hard disk filled with MP3 tracks to have a hierarchical structure as we know it from working with a PC. Using a fixed structure ensures that you do not loose track (literally…) of your favourite songs. After all, an MP3 CD may contain over one hundred tracks, and a hard disk, thousands, so you have to get organised!
