Adventure (V750) SanDisk music question

I have the new Motorola Adventure (V750) with a 2G SanDisk for
storage. I'm attempting to move 1.5G of mp3 files from my computer to
my phone, which has turned out to be a great adventure due to the
total lack of documentation. I feel that I'm close, but I still can't
find the files once in my phone. Here's what I've done:

Downloaded Rhapsody software to my desktop (from Verizon) and imported
mp3 files into the Library
Inserted the SanDisk into my memory reader and formatted it to FAT32
Transferred these files into the Sandisk using Rhapsody (successfully)
Turned off phone and inserted the SanDisk
Powered up phone, which acknowledges the card has been added...

then repeatedly banged my head into a wall trying to find these files
on the music player! I've looked everywhere I can think of and still
can't find the files. Do I need to import using one of the USB to
Micro-USB cables? Seems kind of odd, but I'm getting nowhere fast. Any
words of advice? I'm still searching.

Thanks!

The following solution was emailed to me and I thought I'd share:

I have the Chocolate 3 and what I did is to let the phone format the
card, them move files to the card from my laptop to the music folder
on the card, when I inserted the card to the phone, and went to the
media and to my music, or something like that, I had it make the music
list and presto it was there, I used files I downloaded and some I
copied from my personal cd's, all worked with out a prob, I can even e-
mail myself ring tones that are MP3 based.
