So Lady Gaga's "Born This Way" is still at the top of the Billboard Hot 100 chart for the fifth week straight. That's pretty amazing considering how most of the songs that debut at number one tend to drop the following week. Katy Perry's "E.T." climbed from number eight to number three this week, which is pretty amazing. I'm pretty sure that it'll hit number one either next week or the week after that. Not that I want it to, but Katy seems unstoppable. Britney's "Till The World Ends" climbed from number twenty to number nine, and Ke$ha's "Blow" dropped from number seven to number ten.
