Ok, I haven’t seen any guesses on the first one I posted, so here’s the answer.
It’s also I Want to Know, by Miami Boys Choir. It’s even from the same part of the song – exactly the same part, in fact.
In the original release (on Miami Meets Toronto), the full line was “So now my days are filled with truth, It’s given me peace, feels like my youth”.
When it was performed at Miami Experience, that line was changed to, “So now my path becomes so clear, I’m part of a chain linking thousands of years”.
They actually changed a lot of lines from the song. I like the original version much better.
