I have been enjoying using my new SanDisk Clip Sport for the past 3 weeks. I think the Sport Clip has many user-friendly features and it is a lot of fun to use since I do enjoy learning the ins and outs of my new techie gadgets. The big advantage of Clip Sport is the use of external micro SD cards for playback of mp3 files. I recommend 16 GB cards for optimal use with this player (FirmWare 1.28).
The Sport Clip has 2 modes of music playback, “Music mode” and “Folder mode”.
With either mode, you will likely want to copy music files into subfolders in the 2 Music folders (internal memory or external SD card).
Folder playback mode is a good way to start enjoying your player without obsessing over the ID3 tags. However, Folder playback mode does not have a very useful shuffle mode (no subfolder shuffle). It uses your filenames to play music files in order in one subfolder.
Music playback mode is highly dependent on your curating your ID3 tags. You may want to download the free PC software MP3Tag (v271). Then you will want to optimize your ID3 tags on your music files in the music subfolders in your player. Music playback mode has excellent shuffle modes for all music, or one album, or one artist or one song title. All of this requires patient editing of your ID3 tags.
By the way, the Clip Sport has separate music databases for the internal memory and the external micro SD card. Each SD card will carry along its own music database (excellent for swapping while the player is off).
