How do I get google music to sync to my phone on like a hourly basis or something on my droid inc. When I was stock there used to be an option under google accounts in accounts and sync. I don't see it there now tho.
You might try uninstalling and re-installing the music app from the market. I had the very same issue and after launching the app a few times, I got the message that I had been invited to the beta and it walked me through adding my account.
