I would even say that It's My Life was a 100% pop song.
What are the rock elements on this song?!

Best first singles are RUNAWAY for being THE FIRST single and KEEP THE FAITH. Both marked a beginning,a (new)direction.
Same is true for It's My Life only it marked a crap direction.

However, My fave trackks on the list are KEEP TEH FAITH and YOU GIVE LOVE A BAD NAME.
