After watching several performances by Aguilera as early as she was 11 years old to as late as last year for NBA Finals Game 7, she likes to hold notes and likes to extend the song.
I expect this performance to be about 1:53-1:58 seconds long.
IDK what O/U is, but I expect is to be around this number.
Wait for a SHARP play on this PROP when this time is released.
