Samsung SGH-D807 / D806

I have a bunch of music on my phone, i keep re-arranging them on the computer through my SD file in alphabetical order, but once i put the card back in my phone, the order is messed up again. i just want them in alpha order or whichever order i put them in! It just keeps putting them back to the original order from way back when i started putting music on it. Anyone know a trick???
