Is there a program that does this? I've got software that I can use to get DVD's on my iPad (WHOA THERE! It'll be replaced when there's a Windows tablet!), but I want to get all of music on the phone.
The Zune software and WP7 support the AAC files that iTunes uses. Not a good idea to convert from a lossy file to another lossy file as there is quality that is lost in the conversion.
M4a is lossless
