I am not able to access the google play music because my country isn't supported. I used VPN with a US account and it asked me to login. When I used my email, I receive the error again that my country is unsupported. Is there any other option? You help is highly appreciated.
You have to create a gmail account using an US-based IP address. For that install any VPN app, run it, selecting the country as US, or any other country that supports Google Play Music. Then create a gmail account from the phone itself. Log into it, and you're done.
It's because your e-mail was created using a Philippine IP address.
If you have a Android phone, root it. Note that this voids warranty, and may have a chance of bricking your phone.
