Yeah, thanks much for pointing out the glaringly obvious search function - If that thread you linked or any of the other threads from any of the other forums had actually solved the problem then I would not have had to registere and post this thread. But since you're the only one who took the time to even respond, I guess I have no choice but to ignore your flame.

Anyway:
The "File Explorer" on the Diamond has different directory structure than what I see on my PC when connected as Disk Drive.

I've created a My Music folder on the Diamond and dragged and dropped the mp3's. The Sprint Music item from the TF3d Menu still does not find them - even after clicking library.

On the Diamond the file structure includes folders:
Application Data
ConnMgr
Documents and Settings
My Documents
Program Files
Temp
Windows

On the PC, the "removable drive" has:
Application Data
Live Search
MSMETADATA
Music
My Documents
WMDRM
YouTube

Using the PC, I've dragged and dropped the MP3's into the Music folder; dropped into the My Documents-My Music folder; etc. The Sprint Music Store never recognizes them.

I can open WindowsMedia and navigate to the directory and play them, but they dont show up in Sprint Music.
