The background music is “Nostalgic Fortress”, copied directly from Nintendo’s Super Mario Galaxy 2. I hear the guitar riff in the left audio channel, but I don’t notice it ever clashing with the main melody. It plays varied chords most of the time. When it is monotonous from 0:39 to 0:55, the note it repeats is always a note in the underlying chord, so I still don’t perceive it as clashing.
