what songs don't repeat themselves? 'under pressure' for one

10cc: "Wall Street Shuffle".

"You Never Give Me Your Money" by The Beatles

(although part of that song was later repeated as part of the link between "Golden Slumbers"/"Carry That Weight")

"Lovesick Blues" by Hank Williams

Based on the definition I'm seeing from the answers provided "Good Vibrations" seems to be a choice that was possibly too obvious to be mentioned so far, although it shouldn't fit for this at all since there's several parts that repeat themselves.

That song has a verse and chorus that repeat themselves identically (except for the verse's lyrics) right off the bat. That's not the case with "Under Pressure": The chorus is constant but there is no repeated verse.

"If I Fell" by The Beatles, only the last verse is repeated. But technically no chorus, even.

wait..fuck...I forgot about the 'cos I couldn't stand the pain' being repeated. grr. But still. Similar to 'White Rabbit', in that there's no verse/chorus/verse thing going on. The verses are all just kind of linear.

the DOORS - The Soft Parade
the CURE - Piggy In The Mirror

Doing this here instead of on "songs that are 'rooms with many doors'" because in some ways this is a room with no doors -

The Knife - "Full of Fire"

AC/DC - "Thunderstruck"

am I reading this thread wrong or would "Up the Junction" count here

I guess another way to describe these songs is, instead of A-B-A-B or whatever, they go A-B-C-D-etc..
Last night I listened to Brian Eno's "The True Wheel" (off Taking Tiger Mountain) which does this, and is great.

We're basically asking for 'through-composed' 'non-strophic' rock/pop songs right?

"It's the Most Wonderful Time of the Year" has an interesting structure.

bohemian rhapsody?

I always thought Imogen Heap's "Hide and Seek" did a good job of quickly switching off between structures.

The 'alternate version' of Heroes & Villains by The Beach Boys does this - the first 3 minutes of the video, can't find it as a standalone.

The music on this entire album seems like it's in constant flux.

This is a really interesting thread. I was familiar with many of the tracks mentioned, and a lot of the others I've now checked out. Suggestions vary in terms of what aspect of the music avoids repeating. Like, some are saying that a different vocal melody means a new section, even when sung over a previously repeated section of music. Taken to an extreme, this would mean a music section could just repeat without any variation as long as the singer, or something else constantly varied. This is what's happening in some other suggestions, especially the more electronica or dance-oriented pieces. The hook, be it a bassline, rythmic phrase, sample or simple chord rif is often very short and just repeats sometimes for the whole track. No matter what else is layered over, this is still extreme repetition. However if a song constantly changed harmonically (vocal melody, chord progression..) but had the same drumbeat throughout, would we still think of this as repetitive?

So what I'm left wondering is: What makes a 'section'? I thought for some time sections come down to harmonic progressions, a distinct set of chord changes. But there are loads of great songs where the chorus has the same chord changes as the verse. But so the melody changes? Yes, but not always! Sometimes the chorus's hook's in the lyric... I ended up feeling that a section is a set of chord changes, with a particular melody - vocal or otherwise. If that same melody is then set over different chords its a different section because the notes in it are relative to the root/key.

Here are my 2 of my favourite ABCDE songs:
'Fifty-Fifty Clown' - Cocteau Twins
'Smooth Operator' - Sade

Thanks for reading.

'mother of pearl'

Pretty sure I brought up MOP in some other thread much like this one, as I love its devious construction. Each use of the title phrase is followed up by a different, but similar, line, except the first usage ("I wouldn't trade you for another girl") does come up again at the very end.

it's pretty amazing to work out the structure of 'mother of pearl' and realize it's doing that
