Paramore received acclaim from music critics, who praised the band's maturity and experimentation in terms of musicianship as well as Williams' vocals and overall presence on the album.

"Still Into You" and "Ain't It Fun" have reached top ten positions on various charts in the United States and have been certified double platinum by the RIAA, making Paramore the first of the band's albums to have produced more than one double-platinum single.

In November 2022, the band changed the album cover on streaming services to an image of Hayley Williams shot from behind.

[7] In an interview with Electronic Musician, Meldal-Johnsen stated he wanted "the album to sound very visceral and a little bit less locked down and computerized, more 1981 than 2012, with a nod to 2016.

"[7] On June 29, 2012, the band had confirmed that Nine Inch Nails and Angels & Airwaves drummer Ilan Rubin would be recording drums for the album.

[9][10] In an interview with Rolling Stone, lead vocalist Hayley Williams explained "That whole time for our band was such a dark season.

It was emotionally exhausting, and by the time we got around to the point where we were going to start writing, we just really wanted to enjoy the process of making an album" when asked about the direction of the band after Brand New Eyes.

[16] During the 2013 Soundwave Festival, Paramore held a listening party in Sydney, New South Wales on February 26, 2013, followed by Melbourne, Victoria two days later, run by Australian Music Channel, Channel V.[17] Williams revealed a section of the lyrics for the song "Part II" which the winners were able to hear at the listening parties on a LiveJournal post.

[20][21] The band played an acoustic version of "Hate to See Your Heart Break" on the BBC Radio 1 Live Lounge on April 3, 2013, announcing that on the same night, the full song would be premiered on their official website.

The Self-Titled Tour took the band through 27 cities across North America, including their first headline show at Madison Square Garden.

[28][29] On January 9, 2014, the band, along with Fall Out Boy, announced a co-headlining North American tour dubbed, "Monumentour", which took place from June 19 to August 31, 2014.

[32] The deluxe edition includes a new version of "Hate To See Your Heart Break" featuring Joy Williams, Paramore's first collaboration.

[37][38] A lyric video for "Still Into You" was uploaded to YouTube a day earlier, after the band performed it live for the first time at the 2013 South by Southwest festival in Austin, Texas.

[59] "Hate to See Your Heart Break" was re-recorded in 2014 to feature Joy Williams on vocals for inclusion on the deluxe edition of the album.

[66] Ben Rayner of the Toronto Star stated the band abandoned the emo genre in favor of power pop.

[67] Josh Bell of Las Vegas Weekly called the album a "collection of catchy, energetic pop-rock songs".

"[70] According to Justin Cober-Lake of PopMatters, "[the album has] touches of new wave, pop-punk, funk, alt-rock, pop, balladry, and even a series of ukelele interludes.

"[71] PopMatters also noted that the album "careens between edgy hard rock (“Fast in My Car”, “Now”, “Anklebiters”), ‘80s R&B (“Ain't It Fun”), power pop (“Daydreaming”), tender balladry (“Hate to See Your Heart Break”), and lavish Spector-esque melodrama (“(One of Those) Crazy Girls”).

Mansfield also commented that "Williams' sarcasm seems less forced than her enthusiasm, still, Paramore shows a band determined to get out of the misery business.

"[83] Matt Collar, writing for AllMusic, declared "The record's collaborative foundation crackles on every track, but Hayley Williams, a ballsy, extroverted frontwoman with a voice big enough to stop time, proves unequivocally to be the cunning talent of the band, no matter how vital York and Davis may be".

"[79] Jon Pareles from The New York Times found that the band's songwriting survived the departure of Josh Farro.

"[85] By contrast, Sputnikmusic's staff reviewer Channing Freeman was highly critical of the album, giving it a one and a half out of five as well as calling it, "fucking foolishness".

[96] The album has been a major commercial success worldwide, debuting at number one in eight countries including the UK, Ireland, Scotland, Argentina, New Zealand, Brazil and Australia (where it was the eighth consecutive number one debut on the chart and also the 32nd self-titled album to top the Australian chart).
