The song was also the official song of AirtelChampions League 2010 cricket tournament held in South Africa. Iglesias performed "I Like It" along with "Be With You" in the opening ceremony of Airtel Champions League 2010.
Mash-up artist DJ Earworm has incorporated "I Like It" in three mash-ups. The first mash-up, "I Like To Rock Dynamite", was also dedicated to the AirtelChampions League 2010 cricket tournament and featured "I Like It" mixed with Taio Cruz's "Dynamite" and Queen's "We Will Rock You". The second mash-up, "Don't Stop the Pop", part of Earworm's "United State of Pop" series, features the top 25 songs of 2010, including "I Like It", "Dynamite", and Mike Posner's "Cooler Than Me". The third mash-up, "Party on the Floor", featured "I Like It" and "Cooler Than Me" again, and was made for the 2011 Capital FMSummertime Ball, where Iglesias, Posner, and 13 other artists performed.
"I Like It" has received generally mixed reviews from critics. The song received an average review from Digital Spy's music editor Robert Copsey which gave 3 stars (out of 5) and say that "The verses may feature enough Auto-Tune to make Kesha feel vocally exposed, and the Eurodisco production courtesy of RedOne may have a hint of the Cascada to it, but it's the cheesy lyrics that ensure this stays an unmistakably Enrique affair."Bill Lamb editor of the website About.com gave a positive review and rated it with 3.5 stars (out of 5), enjoying: "Enrique's charming pop falsetto", "Lionel Richie "All Night Long" sample" and the "singalong chorus". Lamb conclued that: " "I Like It" features a retro disco-ish production from RedOne, guest raps from Latin star Pitbull, brief excerpts from Lionel Richie's party anthem "All Night Long," and a shout along chorus of "Baby, I like it!" The overall effect is hit single as churned out by committee. Still, despite the assembly line mentality, "I Like It" retains a certain pop charm.
Erika Berlin of Rolling Stone also gave the song 3.5 stars (out of 5), saying "Enrique is back with his most danceable fiesta since 'Bailamos,'" and added "Pitbull gives us insight into his bedroom: "Tiger Woods times Jesse James equals Pitbull all night long." Cheating never sounded so fun!"
