Feels more like that ambient track for your aloof protagonist strolling about wondering what to do after his muse gets stolen by the main antagonist! Honestly, boss battles tend to be more haunting and/or action packed, making you feel as if this is both going to be tough as well as insanely awesome! On the other hand, the song feels a bit too repetitive with that higher tone from beginning to end.
Sincerely,
