What chart performance theories do you guys have? I mean the reasons why particular songs would debut at high positions, fall quickly, keep re-entering etc. Here are some of my theories:

- X Factor finalists, debut usually at #1 or in top 10.

- Live performances, re-entering songs in the top 100.

- Album releases, causing early debuts to occur.

- Music video promotions (e.g. Gangnam Style)

- Singles only appearing in 101-200 due to lack of promotion.

- Radio plays

- Big falls - X Factor and cover performances.
