Android Media3 ExoPlayer need to perform GET method request on URL or else Response Code 301

Question

I am facing an issue where I've set up a class extending MediaLibraryService and am trying to play HTTP music from a SubSonic URL. The issue is that SubSonic uses GET method to accept the request or else it returns a response code 301 MOVED PERMANENTLY.

Below is the error for more context:

Here is the caught error:

androidx.media3.datasource.HttpDataSource$InvalidResponseCodeException: Response code: 301

My question is how can I make it so the request to get the data is always GET?
