Broken Base: First there was a mild case of this when King of Fools contained tracks that didn't sound like the congregational worship songs from the Cutting Edge days. Then it reached a fever pitch with Mezzamorphis, before finally becoming a full-blown epidemic with Audio: Lessonover?. Subsequent albums generally went for more of a "happy medium" between Delirious? the worship band, Delirious? the rock band, and Delirious? the mainstream pop band, and fan reaction seemed less polarizing as a result, but they never quite seemed to regain the same level of popularity that they had in the 90s.
Covered Up: No, SonicFlood did NOT write "I Could Sing of Your Love Forever".
Epic Riff: Oh so many. "Deeper" is their best known example, but there's also "I'm Not Ashamed", "Bliss", "My Glorious", "Grace Like a River", "God Is Smiling"...
"Obsession" has an epic bass riff.
Germans Love David Hasselhoff: They're surprisingly popular in South America, to the point where one of their final live albums was recorded in Bogota, Colombia, rather than in the US or the UK.
Mondegreen: Martin has a rather... interesting way of enunciating certain words.
"The Mezzanine Floor" contains the line "I'm at this bolted door", which (unfortunately for some fans who were already up in arms over the "hell" debacle in "It's OK") sounded a lot like "I'm at this bullsh*t door."
"God In Heaven" uses the one-syllable pronunciation of the word "Heav'n", as you might hear in old hymns. Unfortunately it's the most emphasized word in a huge, anthemic chorus. So it comes across sounding like "To God in Hell be the glory!"
Narm: The cheery female backing vocals in "Waiting for the Summer" can be rather polarizing. There's a reason why the US audience got a completely different mix of the song.
A good portion of the old Cutting Edge recordings can come across this way if you're not into the more touchy-feely side of contemporary praise music.
Hollywood Homely: Mariel Hemingway's characters of Janet and Louise, with it being focused on how she isn't glamorous enough to be Homecoming Queen.
