[BB] Spotify Premium on Blackberry 8520 and Wi-Fi

[corbetta]

Hi - I have Spotify Premium installed on my PC and on my Blackberry Curve 8520, both on the same wireless network.  Would I expect to see my Blackberry on the devices screen on the PC, becasue it isn't there.  I can see my playlists ect on the Blackberry once set up on the PC, but to download them on the Blackberry I have to do it from the Blackberry over Wi-Fi - should I be able to transfer direct from my PC to the Blackberry over my local network, if I have downloaded to the PC?
