Sandisk Sansa Clip 4 GB (File/Folder Limit)

I have a Sansa Clip 4GB and I put over 2000 songs on it (Low Quality WMA VBR) and I see the songs in the explorer window however I do not see the songs in the player artists or albums, songs. Is there a limit on how many Files or folders the clip can hold? I use MTP mode to tranfer the files and I dragged from windows Explorer

The limit is about 1997 songs. It will eventually be increased in the future.
