I don't know if everyone is doing this, but I'm using Sync to transfer music from an Ubuntu PC to my android phone. This is how I'm doing it: 1. I found a 32Gb micro-usb stick and inserted it in to back of my PC. 2. G-parted to name the stick Music-Sync. 3. Used this trick to convince Rhythmbox that the stick is a mass storage device. 4. Syncronise the stick with the music folder in my phone. 5. Open Rhythmbox and drag-and-drop music on to the Music-Sync device. 6. Also deleting music on the phone from within Rhythmbox.
