Note: This ranking is based on actual performance on the weekly Billboard Hot 100 chart. The ranking is based on an inverse point system, with weeks at No. 1 having the greatest value and weeks at No. 100 proportionately less. Due to various changes in chart rules and methodology through the years, songs have had reigns at No. 1 and on the chart of varying average lengths. To ensure equitable representation of the biggest hits from all years, certain time frames were weighted to account for the differences in song turnover rates.
10. Paramore, "Monster" (2011)
Hot 100 Peak Position: No. 36
Following the tumultuous departure of Josh and Zac Farro from Paramore, the group returned with this single, which led the "Transformers: Dark of the Moon" soundtrack in 2011.
9. Paramore, "That's What You Get" (2008)
Hot 100 Peak Position: No. 66
One of the many breakout singles from Paramore's second studio album "Riot!," "That's What You Get" was featured in the "Rock Band 2" video game and remains one of the band's most fiercely beloved tracks.
8. Paramore, "crushcrushcrush" (2008)
Hot 100 Peak Position: No. 54
As featured in an iPod Touch television ad, the snarling "crushcrushcrush" managed a slightly higher Hot 100 peak than its follow-up from "Riot!," "That's What You Get."
7. Paramore, "Decode" (2009)
Hot 100 Peak Position: No. 33
In between "Riot!" and "Brand New Eyes," Paramore helped soundtrack the dramatic happenings of Bella and Edward with "Decode," which was released as a single from the "Twilight" soundtrack and became a hit on modern rock radio.
6. Paramore, "Ain't It Fun" (2014)
Hot 100 Peak Position: No. 10
Paramore's latest single blends punk, funk, soul and gospel -- and that offbeat combo has given the veteran group its highest-charting Hot 100 hit to date. With time, this one could very well creep up Hayley Williams' list of biggest hits.
5. Paramore, "Still Into You" (2013)
Hot 100 Peak Position: No. 24
Paramore's 2013 self-titled album was preceded by the single "Now," but the starry-eyed love song "Still Into You" was the single to return the group to pop radio, and deliver its first Top 40 hit in over three years.
4. Paramore, "The Only Exception" (2010)
Hot 100 Peak Position: No. 24
Paramore slowed things down on the standout single from 2009's "Brand New Eyes," with the touching ballad "The Only Exception" surprising fans and scoring the band's highest-charting Hot 100 hit at the time.
3. Paramore, "Misery Business" (2008)
Hot 100 Peak Position: No. 26
"That's What You Get" and "crushcrushcrush" were hits, but "Misery Business" is the single from "Riot!" that made the biggest impact on the charts -- and on tour, it's the song that Hayley Williams always invites a fan onstage to help her belt. God, it just feels so good!
2. Zedd feat. Hayley Williams, "Stay The Night" (2014)
Hot 100 Peak Position: No. 18
Hayley Williams never set out to be a EDM superstar, but when Zedd linked up with her for this single, she was ruling the dance floor in no time. Like Zedd and Foxes' "Clarity," "Stay The Night" connected at pop radio, and became a Top 20 hit earlier this year.
1. B.o.B feat. Hayley Williams, "Airplanes" (2010)
Hot 100 Peak Position: No. 2
Williams has yet to score a Hot 100 chart-topper, but so far, she's gotten closest with B.o.B's "Airplanes," the pensive pop-rap track that followed his No. 1 single "Nothin' On You." As Paramore was undergoing behind-the-scenes drama in 2010, Williams was reasserting herself as a multi-faceted pop vocalist.
