A pretty obvious plot hole
Led Zeppelin is a great band and all, but I would imagine that the number of people in America who can listen to Led Zeppelin and only Led Zeppelin, continually, are in the double-digits at most.
They have a very distinctive, riff-driven sound, and combined with the pitchy vocals, there's a limit to how much Zeppelin any one person can take and this person should be way past their limit by now, IMO. At LEAST in the stage of finding them somewhat annoying, but most likely gunning towards 'personal injury' territory from leaping towards the radio dial after hearing the first couple notes of any given Zeppelin song.
They should have chose Pink Floyd for her.
Also, I'm towards the end of episode 4 here and starting to really wonder if this is going anywhere...if this is going to get any better. I sure hope there's some kind of payoff...seems like its starting to push our patience some.
