What, just because of the way the song starts out? Like I said, Misery Signals has uses clean vocals quite sparingly, and Karl does not sound like a 15 year-old. I won't say I don't hear any similarities between the two, but the guitar in "Timing Is Everything" sounding like the intro to "The Failsafe" is no big deal. Stuff like that happens all the time.
That being said, "The Failsafe" is an incredible song.
