Get it on!
Just Press Play
The H320 does not require any type of software other than Windows Explorer (or some sort of file browser). This will be either the H320's greatest strength or one of its biggest weaknesses, depending on your view. When you connect it with the included USB cable it shows up as another hard disk (USB Mass Storage, or UMS). From there all you do is drag and drop your songs and you're ready to play.
This also forces you to do the directory structure yourself. You can do the A-M/N-Z thing to organize by artist/album/song. The H320 supports WinAMP playlists too, which is nice, since the player itself doesn't keep track of anything.
Taking pictures of LCD's is a pain.
A word to the wise, for EAC, you only need the track number and song title. The H320 will read the ID3 tags, but if you're a little dim like I am then the file names will also include artist-album. You'll hit the 52-character filename limit of the H320 pretty quick.
iRiver released its AutoDB to help organize music on the player, but it incurs a significant performance penalty when you start the device. I did not use the AutoDB program. I didn't need no stinking AutoDB! Ahem.
The second method of getting songs onto the H320 is to use WMP10 (Napster also works) and the 'media' USB port. Now you may think I've lost my mind, but WMP10 actually ain't too bad. I won't get into it, but at least when you sync, it won't wipe the H320.
