No, I don't. For phone it doesn't matter which app you are using on PC. It is still the same (Media Player) connection type. As far as I know most applications use even the same routines to put music on handset so it doesn't matter.
Additionally there is also the second way to avoid Refresh button but it is not as good as USB cable so it is rather a detail.
Here you can get application Home Media Server but this solutions has disadvantages:
1. You need to have your own LAN network at home
2. Speed limitation will be always max 54 mbit per second
3. You need wi-fi router so you can have your PC and
N95 in the same net
4. Your media files must be shared with others via Home Media Server so it is bad if you don't use firewall on your router or at least NAT
5. I think that it creates little mess on card in the phone (all music stored in the same folder)
