Not only are Alex Clare and Taylor Swift making debuts -- with 'Too Close' and 'We Are Never Ever Getting Back Together,' respectively -- but Katy Perry has also been dethroned! Her tune 'Wide Awake' was bumped by Ellie Goulding's 'Lights,' which has been out for over a year, but is just starting to gain momentum now. 

Neon Trees are also making huge moves this week with 'Everbody Talks,' which is now at the No. 3 slot, while fun. are also jumping up a few notches with their latest hit 'Some Nights.' Take a look at this week's Top 20 Songs and be sure to tune in to our weekend radio show to hear all of these plus the winning About to Pop song (Bridgit Mendler's 'Ready or Not').
