Which Mode Do I Use

Just bought a Sansa ClipZip 8G and upgraded firmware to 18A using MSC mode as instructed.  I plan to use the ClipZip with Rhapsody, and I’m wondering in normal use (not upgrading to latest firmware) what USB mode I should be using it in, Auto Detect, MTP or MSC.  

If you’re going to use Rhapsoduy with it, you’ll have to use MTP mode in order to transfer the licensing keys that will allow the DRM-crippled files to play. I never advise using the Auto Defect mode. This will screw you up.

Very useful helpful info.  Thanks guys.
