if you have a GS2, get isyncr and the wifi add on and it will transfer your itunes playlists into the gs2.
if you have .m4p protected content it will not read that because it is locked by itunes, but because they are not allowed to do that anymore there are programs out there that will convert all .m4p to m4a or mp3 and you can they reload itunes. they all still work in there and will also work on ANY mp3 player.
The converter i got was from Audial tunebite 8 i think it was $26 or somthing like that but there are others in the range. this one was simple to use and transfered all the meta data too.
there is a new version "9" out now at http://audials.com/en/start/.
good luck.
