Im planning on getting myself a gift soon either 17in. chrome amg rims for my car, a used fretless warwick, or an ipod. I found out they dont play wma and half my music on my computer is wma. Is there a way to convert them into mp3's. I dont want to get a diffrent player cuz ipods the best. If there isnt an esay way i guess i got to get one of the other two.
