I just downloaded a bunch of songs to my Curve---All came from the same source, and have the same extension. Unfortunately, about half of them wont play, although they appear on the media player screen with all the appropriate information. Any ideas.

Protected with DRM? I'm not sure if this would affect it at all, just a thought.

I buy all my music from Napster----They claim that you can load the music on a player. The wierd thing is that some songs from Napster play fine, others don't.

media player has issues with file naming. make sure they are named properly. Has to start with a Proper Character. eg -,`~ are all no good...
