To resolve the issue of TouchTunes not being available in your country, while you are in the US and not using a VPN, follow these steps:

1. Check Location Settings:
- Ensure that your iPhone's location services are active. Go to Settings > Privacy & Security > Location Services, and ensure it's turned on. Then check that the TouchTunes app has access to your location.
