Im trying to get my playlist to stay in order, I just used a media reader card to upload music to the sd card then I manually created a playlist in realplayer but it doesnt stay in order and will not play in the order I want.

My Setup:
Mac OS X
treo 650
all songs are in MP3 format
media card reader

If I have to get a 3rd party software is there one that is compatible w/Mac OS X?
