as opposed to a feature". The first single from 20 Y.O. was thought to be released in February initially. However, it had an initial release date for May. Composition and lyrics "Call on Me" was written by Jermaine Dupri, Johntá Austin, James Phillips, Nelly, Jimmy Jam and Terry Lewis, while production was handled by Janet Jackson, Dupri, Phillips, Jam and Lewis. It is a mid-tempo ballad which samples The SOS Band's 1983 song "Tell Me If You Still Care," also written and produced by Jimmy Jam and Terry Lewis. According to Dupri, lyrically, "It's really just a record about when you need a friend, somebody you need to talk to, just call on a person. It's a friend record. It ain't really a boyfriend/girlfriend record. The way Nelly and Janet are talking is more girlfriend/boyfriend, but it really goes out to friends." Critical reception "Call on Me" garnered mixed reviews from music critics. Andy Kellman of AllMusic picked the song as one of the album's best songs. Jon Pareles of The New York Times called it a "tinkly-twinkly tune," while Thomas Inskeep of Stylus Magazine named it "a lovely little pillow of a midtempo ballad, with Janet singing off Nelly (who’s also singing, which he arguably does better than he raps)." Jeevan Panesar of The Situation picked the song as one of the "Top Three Tracks", praising "its playful melody, easy listening and warm energy," but ultimately, calling it "easily forgettable." Tracy E. Hopkins of Barnes & Noble wrote that the song "won't wow too many fans with its nursery rhyme-like." Spence D. of IGN was mixed, writing, "The obligatory star power guest shot occurs with 'Call On Me' featuring Nelly. Janet goes for her delicate wisp, but it sounds as if she's trying hard to maintain the crispness, straining to keep from cracking. Nelly delivers a slippery grind, making this also the obligatory 'time to get your sex on' number." Don Baiocchi of Blogcritics was mixed, writing that "to kick off a comeback with the mediocre 'Call On Me,' a duet where she actually makes Nelly sing, is just plain wrong. 'Call on Me' wasn't the way to do that." He also noted that "details like the tiny hand claps in 'Call On Me' are bizarre missteps." Evan Serpick of Rolling Stone wrote that "it shamelessly re-creates 'Dilemma,' the St. Louis rapper's collaboration with Kelly Rowland." Johnny Loftus of
