I love Nickelback and Chad Kroeger 😍 It's one of my favorite band. I've recognized the song right away without even reading your post. Hero is a great song and as I see you like it too. Your interpretation is a bit different but very good. You have a pleasant voice, this song suits you.
You're right, musing can be interpretive and that's great.

What this track represents to me is that we all have the ability to be the hero, the one that saves the day, be it for others or ourselves... we just have to be brave enough to take the action need and not wait for someone else to save us, but sometimes we fail to realize the power we have within us.

This should be written in stone and never forgotten! Very nice ans wise words!
