Bit of advice - don't know if it's been said further up the thread because I haven't read all comments BUT:
If you struggle to find music after loading to your SD Card - try dropping one MP3/4 track onto the device as said further up the thread the device sometimes gives in "looking" for music if it can't find an MP3 file on its own memory - then stops looking before it gets to the card.
This happened to me and all it did was put one track on the device and all other music on my card - downside is I have to browse for music every time it start up to get to the larger card file.
