This fixes podcasts, but I noticed that "random album" is still pulling audio books. An option to exclude them too would be great.
What would be really nice is a way to specify a search criteria for the random albums or something like that. That way I could exclude things like comedy and Christmas music or other stuff that's in my library but I don't actively listen to. This is probably a lot more work, so I'll just mark it up to a "it would be really nice" feature.
