Hi Tesslia,
Here is a quick step by step of saving one select song to USB thumb drive:
(Assuming the power is on)
Insert a USB thumb drive
Press GLOBAL
Press FILE
Press STORE
Press ADVANCED
Use the data wheel to select (highlight) your song from the on screen list of objects
Press STORE
Press OK
Give your file a name
Press OK
Press YES if asked 'Save Dependent Objects'
(Manual reference pg.9-16 through 9-21)
I hope this helps.
