It works via Web and Nexus 4 phone with no problems. Might need to email the devs on this one.
Thank you for the reply.

I sent a support email to gMusic and here is the auto-reply:
"If you are emailing because your gMusic abruptly quit working, this is what's up: Google has changed the way some of the back-end programming works. This is causing gMusic to not work right. now. The update has already been submitted to Apple
Thank you in advance!
Unfortunately, since gMusic is a third-party app I don't get any notice when Google decides to change things. Hopefully Apple will approve the update soon."
Hope this helps anyone that is experiencing the same problem.
