I don't think we can add that, altho we can improve it by default. but the thing about file extensions is that it doesn't necessarily represent wether the player is able to play it or not, they just help android/user know their type. for example mp4 is a video so it shouldnt play as music? yet players can play it normally.

ALTHO, u can always chóose folders to exclude from indexer settings
