AllMusic editor John Bush rated the album four out of five stars and called
7 a "solid pop album from an artist with someone to seduce, if not something to say [...] Given arrangements with teeth, Iglesias responds with a set of solid performances, ones that suit his audience but also offer something to listeners who aren't immediately captivated by the faraway look in his eyes on the cover." Caroline Sullivan from
The Guardian described the album as a "drudgesome old mix of arena rock and
Our Tune weepies." She called
7 an "insipid record. If you buy into the idea of sonny-boy as sex god, you'll be in a lather over the innuendo-laden ballad "Addicted," which appears in four different versions. If not, don't bother, unless you've got a soft spot for the drive-time "rock" that fills in the gaps around the ballads." Similarly,
Entertainment Weeklys Michael Endelman wrote: "On his third English-language album, Iglesias abandons frothy Latin pop for glossy arena rock, and it proves to be disastrous. There's nothing here that's as undeniably anthemic as the prom-night favorite "Hero," from 2001's
Escape. And his breathy, overly emotive vocals are better suited to disco fluff and ballads than to crunchy rockers, leaving listeners with an awkward disc stocked with cliched lyrics and generic melodies."
Los Angeles Times critic felt that "unfortunately, this derivative pastiche of that era's rock, new wave and folk-pop, spiced with modern electronic-dance flavors, is about as imaginative as the album title," while
Nows Elizabeth Bromstein found that
7 was "just flat, overproduced pop with dim lyrics like "It's the way you touch me baybay." It's just got no punch." ==Commercial performance==
