Well, he's certainly lined up a crack team of collaborators, having divvied up equal time in the lab - sorry, studio - between RedOne, Cuban producer Descemer Bueno and his old 'Hero' buddy Mark Taylor. The former's contributions include the hit trailer single 'I Like It', a frothy pop-rave stomper that manages to sound unmistakably Enrique despite featuring a rather jarring sample from Lionel Ritchie's 'All Night Long' - no mean feat.
Elsewhere, Euphoria flits between the sentimental Iglesias of the 'Hero' and 'Bailamos' era and the new, Down With The Kids Enrique. The latter is generally more entertaining, with the robotic vocal effects of 'Everything's Gonna Be Alright' and rave-tinged production of 'Dirty Dancer' - which features a typically cocky cameo from Usher - providing the album's highlights. Meanwhile, the standout slowie is probably 'Heartbreaker', on which Quique's trademark trembling vocals hark back to the days of those million-selling ballads.
As with many experiments, the end result here is not necessarily what Iglesias may have intended. For reasons unknown the UK edition of Euphoria contains just two Spanish cuts - four fewer than its US counterpart. Perhaps he's discovered our shameful secret - that we Brits just aren't that well-versed in the language of love? Whatever, the lack of confidence in the Spanish-language material exposes the fact that Euphoria is a mixed bag of a record which tries a little too hard to please the disparate elements of his fanbase. It's hard to avoid the conclusion that Iglesias may have been the subject of this experiment rather than the scientist behind it.
