Automatic file download?

Hey Guys,
So I want to create an app where the user can play/listen to Music.
Now my files are actually too big to be uploaded to App Inventor server, but I saw a guy on YouTube showing how to pass the upload limit by just reffering to the file on the internet (uploading it somewehre else and reffering to it on the app). But for this the user must have internet connection while using the app. And wanted to ask if its possible to let the app automatically downloading the files when opening the app the first time and the let the user playe the music offline (through the app).
Is that possible and how?
