Playlists

I’ve downloaded playlists from iTunes and removed iTunes DRM.   I can download to the music folder on my sportclip plus, the device syncs/transfers the songs, sounds like the processs has worked.   However, when I dis onnect and look for the songs on the player they only show up under albums as “unknown albums”.   They don’t show up as artists or playlists.   How can I fix this?   

Cheers,
