Nice remix, but I'm not a fan of the random key change at 1:21. You're far from the only person to do this - it's a trick that been done to death by popular music, but IMO it's a very bad example to follow. They usually do it to hide the fact that they're repeating lyrics, but only succeed because they create an even more jarring disconnect in the music which distracts listeners away from the lyrics. It's the musical equivalent of covering up a bad odor with an even stronger one.
