I do love covers of songs, and actually frequently prefer covers to originals.

My perspective comes from having a long list of want-to-record fics and having limited recording time in which to do them, so given those parameters, recording a story which is already available in audio form doesn't make sense to me. But then again, I totally see podfic as an accessibility feature and don't really consider myself an artist.

If someone else chooses to record a story that has already been recorded, that's certainly their prerogative - I wasn't attempting to speak for others, merely expressing my own feelings on the subject.
