A band shouldn't necessarily be blamed for its imitators -- ask the Cure or the Grateful Dead. But Coldplay follow-throughs are redundant; from the beginning, Coldplay has verged on self-parody. When he moans his verses, Mr. Martin can sound so sorry for himself that there's hardly room to sympathize for him, and when he's not mixing metaphors, he fearlessly slings clichés. "Are you lost or incomplete," Mr. Martin sings in "Talk," which won't be cited in any rhyming dictionaries. "Do you feel like a puzzle/ you can't find your missing piece."

Coldplay reached its musical zenith with the widely sampled piano arpeggios that open "Clocks": a passage that rings gladly and, as it descends the scale and switches from major to minor chords, turns incipiently mournful. Of course, it's followed by plaints: "Tides that I tried to swim against/Brought me down upon my knees."

On "X&Y," Coldplay strives to carry the beauty of "Clocks" across an entire album -- not least in its first single, "Speed of Sound," which isn't the only song on the album to borrow the "Clocks" drumbeat. The album is faultless to a fault, with instrumental tracks purged of any glimmer of human frailty. There is not an unconsidered or misplaced note on "X&Y," and every song (except the obligatory acoustic "hidden track" at the end, which is still by no means casual) takes place on a monumental soundstage.

As Coldplay's recording budgets have grown, so have its reverberation times. On "X&Y," it plays as if it can already hear the songs echoing across the world. "Square One," which opens the album, actually begins with guitar notes hinting at the cosmic fanfare of "Also Sprach Zarathustra" (and "2001: A Space Odyssey"). Then Mr. Martin, never someone to evade the obvious, sings about "the space in which we're traveling."

As a blockbuster band, Coldplay is now looking over its shoulder at titanic predecessors like U2, Pink Floyd and the Beatles, pilfering freely from all of them. It also looks to an older legacy; in many songs, organ chords resonate in the spaces around Mr. Martin's voice, insisting on churchly reverence.

As Coldplay's music has grown more colossal, its lyrics have quietly made a shift on "X&Y." On previous albums, Mr. Martin sang mostly in the first person, confessing to private vulnerabilities. This time, he sings a lot about "you": a lover, a brother, a random acquaintance. He has a lot of pronouncements and advice for all of them: "You just want somebody listening to what you say," and "Every step that you take could be your biggest mistake," and "Maybe you'll get what you wanted, maybe you'll stumble upon it" and "You don't have to be alone." It's supposed to be compassionate, empathetic, magnanimous, inspirational. But when the music swells up once more with tremolo guitars and chiming keyboards, and Mr. Martin's voice breaks for the umpteenth time, it sounds like hokum to me.

MUSIC Correction: December 24, 2006, Sunday An article on June 5, 2005, critical of the band Coldplay referred incorrectly to the groups Embrace and Travis. They released records before Coldplay did; they were not part of a generation of one-word bands spawned by Coldplay. A reader's e-mail message on Dec. 11 pointed out the errors.
