Well the easy way to do it is if you have a SD memory card in your phone. Then all you would have to do is take your card out of your phone and put it in your computer and copy the music from your computer right onto the memory card and then place it back in your phone. You should also have a cable cord that came with your Blackberry. You should also be able to just take that and place one end in your phone and the other in your computer and transfer or copy the songs that way. Hope this helps!
