hi,i am new to ipad2 and have macbook pro too,i would like to have a playlist of music on my ipad2 and i know i can sync music from my pro say from my cds but i would like to be able to have an app on my ipad that will let me listen to a playlist,i favoured spotify but it looks like you have to pay for the premium service,can anyone point me in the right direction?thanks .
