title: Is it possible to add custom metadata tags to music files?
body: <p>I am working on a music player application and I'm not happy with the current standard for music tags. I would like to extend on the current ones. Is it possible to add custom metadata tags to audio files (MP3, OGG, FLAC, WAV)? Obviously only my application could read this metadata. Would adding custom metadata corrupt the files so they can't be played correctly by other players?</p>
