odd, I thought I'd posted this already - if it shows up twice I'm sorry...
Jazzyvee,
I think all recording situations are uncomfortable simply because of the nature of what it is. Although I was never a "mainstream" studio guy I did do a fair amount of that work back in the day. And when that was happening it helped me gain confidence and lowered the stress level. I always enjoyed the camaraderie and amazing skills of the musicians I got to work with, and even the reading gigs didn't worry me too much when I was doing more of that... But that first session after being on the road or not recording for a while was tricky for me and tripped me up a couple times.
There's an interesting psychology involved in recording work. I am NOT a good salesman, particularly when trying to sell myself. Some guys are amazing at self-promotion but that was never one of my skills. But in a recording situation you need to be confident in what you're doing so that the Artist and Producer know they've hired the right person. You are NOT the only one at the session who is nervous! In fact, the Artist should be having the time of their lives so it's very important to support that feeling and exude confidence in the music and everybody's part in it - including yours. That's no place for you to voice doubtfulness or otherwise dampen the mood, you gotta be positive and supportive.
Obviously you have to PLAY great and do everything you can to make the music great, but the psychological support and good vibes role is nearly as important.
Not sure if I've explained that very well, but it's the reason that I encouraged you in this thread to confidently deliver your track and let them know that "THIS IS THE ONE".
As to your other question, depending on how involved I am with the project I'll most often end up buying the album from iTunes. Even if the Artist offers to send one I'll do that to support the team (and they love that response).
Anyway, glad that all worked out for you. I hope the band, producers, and engineers all call you for more. "Get that guy with the HUGE tone!"
