This is a bit of a problem for me, and one of the few annoyances about the A818. Most of the time it's no big problem, but once in a while I'll want to change the genre of an album if I don't think it's quite right (this is kind of important to me, since I like shuffling songs by genre), and to do that I have to delete the album from the player, change the genre of the album on my computer, and then transfer it to the player again. If I could just change the ID3 info of the files while they're on the player, it'd be so much quicker.
I've only had the A728 for a few days now, but it seems to operate the same way. I need to delete files from the player and then drag & drop the updated files to the player.
