After poking around in the Scribd audiobook section, I think you're much better off with the library - Scribd is great for readers who tear through books like tissue paper (er, that's me) but probably not so much for audiobooks, which don't have the straight-to-cheapo-digital publishing option.
I have had trouble finding audiobooks that I like, actually. I loved LOVED The Goblin Emperor, which is one of my favorite books anyway, but have had trouble getting into other ones. Bug likes audiobooks a lot, and is similarly picky. Any fantasy suggestions, or is that not your area?
