I prefer to hear an adult Michael sing love songs, so I don't think I'd vote for any he sang as a child.
I voted for Dangerous, because of Remember the Time, In the Closet, Give In To Me and Will You Be There.
Also because Dangerous is hands down my favourite album. Ever.....of all time.
BAD would be my next choice because of Liberian Girl, TWYMMF and IJCSLY. Honestly, there are beautiful love songs on every album.
Then there are so many other beautiful ones that weren't even on an album, or at least not a major release, like "For All Time", "On the Line", "Fall Again" and "Beautiful Girl". SIGH.
