Playlists aren't always music...

In a future release, can you change the playlist terminology to reflect a broader use of the app? Right now it assumes that the playlist will only contain music. The icons are musical notes, and the files are referred to as "songs." For our use, the playlist doesn't contain music, but speaking, as in classes and teachers. Can you use different terms and icons that can be either? A microphone or speaker for an icon, and use 'clip' or 'audio' for text description of the files.
