Personal Top 25 (Week Of May 31, 2014)

Really Don't Care (Demi Lovato ft. Cher Lloyd) debuts at No.1 becoming the 1st song to do so
It's On Again (Alicia Keys ft. Kendrick Lamar) returns to the Top 10 at No.2
Team (Lorde) ties with Addicted To You (Avicii) for Biggest drop off from the charts

This week data is from 17/5/2014 to 23/5/2014.
Fun Fact: Really Don't Care (Demi Lovato ft. Cher Lloyd) becomes the 1st No.1 debut. Originally, Shake It Off (Taylor Swift) was the 1st No.1 debut
Also, this is the 1st official chart week where I had a full Top 25 but since data is lost. I decided to recreate the chart week and added 3 weeks before this week as there were some songs that charted with no peaks before this week.
Finally, the peaks and chart weeks for all songs might be affected especially 2014 and 2015 songs since the data is only from this week till the current week. However, I do not know where they rank for each week so songs peaks and chart weeks will be affected by the new arrangement.
