Hey, Shawn, welcome aboard.

You'd be surprised at how many long time musicians join the site for the very same reason you did. Myself included many years ago and I've stuck around for almost a decade now.

Looking forward to hearing what you have to offer so make use of the Listening Post area once you've gotten some stuff recorded.
I can say from experience that your iTunes sales will definitely improve from your exposure here. Just be sure to stream your tunes rather than give them away for free and you'll do some pretty good business as long as you have quality material.
