Love Somebody (Maroon 5 song) [SEP] Composition
"Love Somebody" is a dance-pop song with a length of three minutes and forty-nine seconds. It is set in the key of C major and its instrumentation consists of piano and guitar. Rob Sheffield of "Rolling Stone" described the song's synth hook as the Sly Stone-meets-Eurythmics. According to Chris Payne of "Billboard", Tedder and Zancanella's influence is all over the song and inches through the verses "before bubbling over just before the chorus kicks in." Adam Markovitz of "Entertainment Weekly" in a review of the album, wrote that the song together with "Daylight" have "thickly" produced choruses. Lyrically, "Love Somebody" equates love and physical intimacy, with Levine singing: "I really wanna love somebody [...] I really wanna touch somebody".
