why are some of my songs not currently available in my country or region

Hello mpagel18,

Media availability varies by region, this is expected behavior.

Depending on your country or region, you might not be able to buy, download, or subscribe to certain types of media. The availability and features of certain apps, movies, and more can vary. If you think an app or other media should be available in your country or region, contact the developer or publisher directly.

This information and more can be found here: Availability of Apple Media Services - Apple Support
