Number one reason I just can't listen to podfic. Disregarding the awkwardness, there are a lot of voices I can't stand listening to and often, when the voices are okay, the recording quality sucks.

There are one or two narrators on the NoSleep podcast I really can't listen to either and sadly, one of them reads a lot of stories, so I often end up skipping a lot of tales. It's what's holding me back from buying more than the one season pass I bought in the past.
