How to transfer music to my motorola hint?

I recently switched out my motorola rocker for a motorola hint. I am using the sd card from the rocker in the hint and the pics showed up but when I try to play the music, it says the does not contain supported music files. What should I do?|||Well you have to make sure that the music is a mp3 type files because that certain phone only works with mp3 files . So what I did is I downloaded limewire and got all the music there . Hope I could help.
