I left this message on Amazons review site. It may be of use to you folks:
I wanted a new MP3 player that would hold all of my media. 32G was the ticket for my 20G of media. Sadly, this player won’t play the tracks in track order. I bought some music her on Amazon. My several year old Clip Zip plays the music in the proper track sequence, while this new one plays them in some odd order. I do NOT use shuffle. I tried to get the MP3 tags very simple (tracks changed from 1/15 to simply 01, disk changed from 1/1 to 1). I don’t know what it uses to determine sequence, and SanDisk players used to get this right. This one does not. I even updated to the latest firmware (1.04). I have always liked my previous SanDisk players. This one disappoints due to it playing tracks in the wrong sequence. I will hold out for a firmware update that addresses the problem. SanDisk->Use the MP3 tags to build the sequence list. I would rate as 5 stars if the track list was correct. This is VERY important to me that a player plays in the right sequence.
Update: I have 318 albums, for about 4,500 songs contained in just less than 20G. So when I loaded all of it to the player, I noticed some albums don’t play in the right order. I then deleted all music from the player, then picked out about 6G to load into it, including the albums I noticed didn’t play in the right sequence. Well, now they play in the right sequence. I have yet to figure out how much I can load up before the problem returns. For now, I will not load my entire library. Maybe a future firmware update will address the issue.
