My friend and I had a habit of blasting Spice Girls every time we were on a highway (or at a stop light, windows down of course). Personally, I have a few. Some pop stuff, like Heart Attack (was that demi lovato? I cant keep them all straight), bad Norweigan power metal (oh Mortiis, I'll never stop loving your goofy music videos), and... some My Little Pony fan-music. A lot of it is straight-up-awful, but seriously plug "MLP Awoken" into a youtube search. Its better than you'd expect.
