Once again, Alex and Sierra have claimed the championship spot on the Top 10 Video Countdown! The duo's 'Scarecrow' is in the No. 1 slot.

Rilan's 'Chemical' scored the runner-up spot, while Fifth Harmony's 'BO$$' took No. 3 and Ed Sheeran's 'Don't' came in No. 4.

Paris Hilton's 'Come Alive' took the No. 5 spot, followed by Katy Perry's 'This Is How We Do' (No. 6), GRL's 'Ugly Heart' (No. 7), Taylor Swift's 'Shake It Off' (No. 8), Coldplay's 'True Love' (No. 9) and Iggy Azalea's 'Black Widow' (No. 10).

It's the end of the month, which means any videos that were released before August 2014 are officially off the countdown. However, that means there's lots of room for the amazing videos coming soon!
