How to add music files without WM player?

Hi guys,

I'd like to add music files to the microsd card (without syncing using WM on the PC) and then access them from the Windows Media Player or perhaps "Sprint Music", whatever thaaat is.

So I connected the TouchPro to my MacBook Pro using the data cable - selected Disk Drive, making it viewable on my Mac desktop - and put a folder on the microsd card called "My Music" with subfolders similar to how iTunes would organize them, then finally copied a few mp3's to the card. Then I choose Update Library from the WM Player. It found 4 files, it said, but only listed ONE FILE in All Music. SO, it did find A FILE that was put on the sd card, but not MOST of them.

Any ideas on how to get WM player - or Sprint Music - to recongnize all the music files I put on the microsd card?

Thanks,
Tim
