In a fun "battle" with the service that distributes music to music stores like Apple Music or Spotify right now. The band I am in has songs that are about 75% Japanese and 25% English on our new release. When I submitted the release, I needed to choose a language for the release. 75 is more than 25, so I selected Japanese. Then, with each song, I set the language to what language it is in. I clicked send and waited to hear from them.

I got a form email saying due to some issue, one of the stores can't accept it. I wrote back asking what the issue is and got a response saying due to some language issue, they couldn't submit it.

As a test, I resubmitted the album and set the release language to English and set the tracks to their language. I am waiting to see if English is okay for whatever store is blocking submission.

I don’t really get why I need to set the language at all for our music though.
