Bro!
If I wasn't still banned from the 'chat' feature of this site, I would tell you to meet me there as I have so much advice I could give you relevant to what it is I see you need!
If I was to write you a response here, I feel it would end up wayyy too long, as I have a lot to say. But don't worry, there will certainly be some value for you in this response...
Firstly, I too am persuing my dreams in music, so I can really understand the importance and your desire for skills in networking! In relation to your question can 'game' be used for social stuff - yes it can! However, most 'game' stuff is a bit(very) weird, and you don't want people thinking you're 'weird' now do you?
I would highhhly recommend you checking out this guy and getting your hands on his conversation e-book...
http://www.yourcharismacoach.com/
Amongst other things, this book will help(lots) with...
- Getting over your fear of rejection/ (how to never get rejected again)
- Never having a 'bad' conversation again
- How to 'break the ice' smoothly
^I listed only these three things, as they seem to be your three biggest worries/things restricting you. But this book will teach you so many useful tips on how to become a conversational master... and best of all... it's FREE!!!
I can only say I wish someone had shown me this book before I started 'gaming'.
Right, before I sound like a bad marketing campaign, I'll leave you with that. It's your choice what you do with it, I only hope it helps you as much as it has helped me.
Love
