I had just downloaded doubletwist and opened an account. When i opened the application, it automatically started syncing with all of my music files on my computer. Thats fine. But the majority of my songs are formatted in wma. And my pre does not support wma files. When I hook up my pre to the doubletwist, will it automatically convert the songs to mp3 or anything compatible for my phone? If not, then will anyone tell me the best way of converting over 1,000 songs into mp3 without paying a penny.
