Is Michael Jackson Challenging Adele's '25' From The Afterlife?

'Cause... this is 'Thriller.'

In one corner, we have the artist with the best-selling album of all time. In the other corner, we have the artist with the best-selling album of the 21st century.

Michael Jackson's Thriller is resurfacing on the same day as Adele's new 25, and for 7 days straight (Nov. 20 through Nov. 27), the king of pop's iconic record will be available for free.

Free?

The most most popular musical masterpiece in the world... for free?

That's correct. Google Play is giving the US the chance to fill in its musical library with an important staple in celebration of Thriller's 33rd anniversary. Assuming there's a person on this planet that doesn't already have a copy of the world's best-selling album, MJ's record could see a major spike in downloads this week.

Will it be enough to defeat Adele's 25 downloads this week?

Not likely -- especially since Adele's record is hot off the presses. But hey, not everything's a competition, and we can all just sit and be thankful that the two icons are making their way to our ears again.
