php - Laravel Public vs Storage directories for audio files -

i little bit confused in directory should put .mp3 files in laravel 5. public/ , first choice mp3 can considered media (like images stored there) storage/app , according docs directory kind of recommended purpose. i don't mind being able url of these audio files since serve stream (to somehow prevent downloads, lol). any advice? thanks. guess depends on whether want direct public access or not. public/ simpler. in there can link directly. js or css or images resources. storage/app more secure, no way access directly. that's use (actually think i'd storage/app/audio specific) have more control on how accessed.
