Mine has to be Peripetie by Arnold Schoenberg, it is meant to be awful though so he has done a pretty good job though. Never heard of it. Of coarse you've never heard of it take a listen. (That link isn't my video btw in-case you think I'm just doing this for views on a you-tube video)
Journey's "Open Arms". It's so over-wrought and, for some reason, it has been playing over the PA in every single strip club I have ever visited.
I know it should remind me of strippers, but it only reminds me that the song is such a cheesy anti-love song, it's acceptable to play during a lap dance.
That stupid Billionaire song really gets on my nerves. The last thing I want to hear when I turn on the radio is Bruno Mars whining about how much money he doesn't have when he's doing a lot better in this recession than most people in this country.
