When I sync music on to my eclipse mp3 player it goes into a folder and then I cant play them.

SOURCE: mp3 player has no music

The player has a Recorder Mode and an MP3 mode. The player defaults to recorder mode for some reason, this is probably why you cannot see the songs. To switch to MP3 mode you have to hold down the MODE button for more than 2 seconds. Then you should be able to see the songs.

SOURCE: I tried to sync music

I called Mach Speed technical support at (580) 272-0035 and they told me that model CLD2PL cannot handle music being in folders. So I removed the folders from the mp3 player and copied over the music again (as single files) and now it works. Hope this helps.
