Best alternatives for iTunes on my mac?

I’m getting very tired of dealing with the buggy, bloated nature of iTunes. After a complete deletion and reinstall and then a nuke an pave of my entire operating system, it’s still acting up and I’m tired of it. More than anything else, I need a decent podcatcher app. The vast majority of my listening time is spent on podcasts although the ability to cope with my Audible book library and my iTunes purchased music would be desirable bonuses. I don’t currently use a smartphone so that’s not an issue. An absolute requirement is the ability to work with my old 160gig iPod.

Do I have any good options?
