Insomniac is the eighth studio album, and fourth English-language album, released by Spanish singer Enrique Iglesias. The album was produced by John Shanks, Kristian Lundin, Sean Garrett, Anders Bagge, Jesper Andersen, Mark Taylor, Stargate, and Maratone. It also contains his first collaboration with a rapper, Lil Wayne, as well as a cover of indie band Ringside's "Tired of Being Sorry". This album is said to be different from his prior albums, incorporating a more contemporary pop style. As well as the aforementioned hip hop collaboration, the album also includes elements of R&B and Latin pop. It was released worldwide on June 11, 2007 and in the USA on June 12, 2007.
"Sometimes I take a pill to sleep, or two or six. But I guess that is the way it goes - when you put three years into making an album, you also become a bit of an insomniac. I have always been more of a night person. I never lay vocals onto any song before eight or nine at night. I always work at night. I go to the studio at six or seven in the evening and leave again at six in the morning. So in a way the album was done by night."
The album is his first for four years since 7, which failed to match the staggering sales of 2001's Escape. "Insomniac" is not just the title of the album, it is also a fact of Iglesias's life, who says he often takes sleeping pills to get a good night's rest. Iglesias recorded most of the album in the evening and early hours of the morning. He wrote more than 50 songs before settling on 12 that he felt were strong enough to put on the album.
Insomniac runs the gamut of emotional anxiety, moody pining, enduring love and a constant sexual pulse. He says he wrote hundreds of songs for the album. "The more songs I wrote, the best chance that I could pick 12, 15 great ones. It's not that I wanted to make a musical change, I just wanted to write good songs." The album is said to be Iglesias' most diverse to date. It features a song titled "Miss You", which he has dedicated to his girlfriend, former tennis star Anna Kournikova, as well as a track, "Push", which he performs with rapper Lil' Wayne -- a big departure from his usual material. The first single, "Do You Know", has become known as the "ping pong song" because of its stand-out beat. There is also a cover of indie pop band Ringside's "Tired of Being Sorry".
"I wanted to write about love because it is the one thing that we all identify with. Everyone knows what it feels like to be with someone you love, and to fall out of love. You suffer because of love and then love makes you happy."
Allmusic reviewer Stephen Thomas Erlewine gave to the album 2.5 out of 5 stars, writing: "'Insomniac' is pushed to a younger audience. But Enrique is too much of a crossover guy to spend the entire album doing the nasty. Sometimes, he pushes too hard in either direction, but sometimes Iglesias strikes the right balance between crossover pop and stylish retro-new wave production. What works on this slick, snazzy makeover is what always works for him: the ballads and the middle-of-the-road pop tunes. They may not be hip, but they're part of the family tradition, and when he sticks to them, he's as good as ever." Lauren Murphy from Entertainment.ie criticized the songs, writing: "Every track here is either a sombre, mumbled, slow-moving number that sounds dated and cumbersome, cheesy radio-friendly dirges that have been done a million times before and better or are just so amateur-sounding that they're embarrassing." Jonathan Bernstein from Entertainment Weekly wrote "Insomniac sees Iglesias possessed by the vengeful spirit of Toad the Wet Sprocket ("Stay Here Tonight"), outshone by Lil Wayne on the plodding club banger Push, and, yes, upstaged by a sampled Ping-Pong ball on Do You Know? (The Ping Pong Song)."
Jerome Blakeney from BBC Music gave to the album a positive review, stating that "He remains the king of latin-tinged heart-tugging and at least half of this album keeps him firmly on top." Joey Guerra from Houston Chronicle also gave to the album a positive review, writing: "Insomniac's secret weapons, however, are its ballads, which cast Iglesias as — of course — a sensitive, soulful Spanish lover." Scott Shelter wrote for Slant Magazine that "The ballads are disappointing because the rest of Insomniac isn't half bad, and if all of the ballads were like the acoustic 'Don't You Forget About Me", Insomniac would've been worthwhile effort; instead, it's a case study in ironic album titles."
The album debuted at number 17 on the Billboard 200 chart, with 45,000 copies sold. However, the previous album, 2003's 7, began at number 31, but with 77,000 copies. It also debuted at number 3 on the UK charts were it would be certified Gold. The album went Platinum (or multiplatinum) in countries such as Ireland, Russia and Poland.
