Backed up iPhone, didn't transfer music
Old laptop went kaput, so I got a new one. When I plugged my iPhone in for the first time, I backed it up. I then had to erase and synch in order to link it with my new computer. After it was erased, I restored from back up, and now there is no music on the phone. Have I lost everything, or is it still possible to recover? My iTunes library has more music than can fit on my phone, so I would have to sort through everything all over again.
Thanks
