The format of the database is entirely different. It's optimised for querying large databases with a small memory footprint, where the disk is spun up.
You can select music by playlist (only one level deep, though), and by genre, artist and album. Once you've selected a genre, artist or album, you're prompted with a list of the tracks, or you can select all matching items. In this respect, it's slightly better than the empeg-car.
I'm assuming that you add tracks into the database using software on the PC. When you do this does it physically copy the track you give it, or does it just link to where the file already is no the PC's harddisk.
