I don't think, that is what i searched for. Couldn't it be as easy as VB.net to VB.net, over sockets or Base64 and TCP ?
This is how it should work:
On my PC (VB.net) is the server and on my phone is the client. If the client connects, the sever sends a list of songtitles, which the client receives and shows. Then you choose a songtitle on the client and it sends the title to the server. There the server sends the song which is related to the title and the client receives and plays the song.
