People can't wait for the weekend." Also in an interview with MTV News in late 2010, Avril Lavigne spoke about being included on the song, saying, "It was really exciting because 'I'm With You' is one of my favorite songs that I've done, I always love performing it."

"Cheers (Drink to That)" is a pop rock and R&B song. It contains samples of Lavigne's song "I'm with You", which is featured on her album Let Go (2002). According to the digital music sheet published at musicnotes.com, the song is written in the key of E major and is set in simple time with a moderated hip-hop groove. Rihanna's vocal range in the song spans from the low note of E₃ to the high note of C₅. Lyrically, "Cheers (Drink to That)" is a party or drinking song, and this is exemplified by the verse "Life's too short to be sittin' around miserable/ People are gonna talk whether you're doin' bad or good/ Don't let the bastards get you down/ Turn it around with another round." The line "Don't let the bastards get you down" is taken from a mug that LP's late father used to drink coffee from. According to Ryan Dombal of Pitchfork, the lyrics sum up the general sentiment of Loud, which as an album is less reflective of tabloid speculation than her previous release, Rated R (2009).

On its release as a single, "Cheers (Drink to That)" received positive reviews from music critics. Mark Savage of BBC Music described the song as "a funky, loping guitar groove for a night out on the town," which Rihanna dedicated to "all the semi-alcoholics in the world." Robert Copsey of Digital Spy praised the interpolation of Lavigne's song, calling it "unbelievably catchy", as well as commenting that the track would succeed in bars and clubs thanks to the lyrics referencing alcohol and going out. Jon Pareles of The New York Times commented that "Cheers (Drink to That)" is written for "barroom singalongs." According to Leah Greenblatt from Entertainment Weekly, "the Jameson-swilling, TGIF-toasting 'Cheers (Drink to That),' folds a left-field Avril Lavigne sample into a crunked party anthem."

Amy Sciarretto of PopCrush also commended "Cheers (Drink to That)" and its musical style, writing that "the song is infused with the tropical island groove that she has explored on 'Loud' and which harks back to her upbringing in Barbados." Sciarretto also noted that "Cheers (Drink to That)" would be very popular in bars and clubs because of the lyrical content. Andy Gill of The Independent called the song an anthem with which the weekend can start. Thomas Conner [de] of the Chicago Sun-Times said that "Cheers (Drink to That)" is the best song on the album, saying "[the song is] a wise, world-weary paean from a gal at the bar who's seen some stuff, has moved on and wants to buy everybody a round of fruity shots." However, Chris Richards of The Washington Post stated that "Cheers (Drink to That)" did not meet his expectations and commented that the song is a lowlight in Rihanna's career, stating "'Turn it around with another round,' Rihanna bellows over the mid slog, as if setting ad copy to music."
