Not just half... Some companies even make IPA Variety Packs! Where the hell is my Stout variety pack? Or my bourbon barrel aged ale variety pack!?
Also, yes, if they listed what hops were used I might actually try some IPAs instead of assuming all of them taste like a bitter flower that's trying to make me gag.
It's definitely overkill for just one audio book, but Plex can do that, I'm pretty sure. And if you wanted/needed to you could also stream it from that PC to just about any other device on your own network for free (they have paid options that wouldn't apply to your situation; probably being able to stream your media server content to remote networks).
