- Ear Worm: "Money". Its unusual time signature (7/4) (except for the solo, which is also awesome) and bass riff don't much help.
- Epileptic Trees: "The Dark Side of the Rainbow".
- Gateway Series: This album has introduced lots of people to Progressive Rock, as Pink Floyd is a gateway into prog and this is usually the first Floyd album most fans start with.
- Growing the Beard: Though they had some success with The Piper at the Gates of Dawn in their native Britain, and their previous album Meddle is considered to be much better than their last couple albums, with "Echoes" considered to be a major step forward and where their beard started to grow in particular, this is the album that truly made Pink Floyd the ubiquitous rock 'n' roll juggernaut that we know today.
- Harsher in Hindsight: "The Great Gig in the Sky", after its composer went there.
- Hilarious in Hindsight: All those clocks going off at once are bound to remind one of Back to the Future.
- Just Here For "Money": Something Waters and the rest of the band have expressed irritation with, and rightfully so.
- Memetic Mutation: The album cover has spawned a ton of parodies and homages, with one of the best known involving Pokémon's Eevee and its evolutions◊.
- Sequel Displacement: Some casual fans think it's their debut album.
- Some Anvils Need to Be Dropped: Quite a few songs on the album qualify, but "Us and Them" really takes the cake. Its message is simple, universally applicable, and as subtle as a hammer to the face: Everyone is capable of being inhumane, and trying to dehumanize your supposed enemies as some monolithic "Them" has never made the world a better place. Put all that together, and you've got one of the best protest songs in the history of rock n' roll.
- Complete Monster: Satan is a Fallen Angel who has pledged to one day become more powerful than God and turn Heaven itself to ash while destroying as many human lives as possible. He has used The Bermuda Triangle as a portal to pull unsuspecting vessels and planes onto the dark side of the moon, killing hundreds if not thousands of innocent people. When the crew of a deep space mission travels close to his Derelict Graveyard, he possesses and slowly kills them off one by one while turning them against each other for nothing more than his own sick amusement. Even the last crew member blowing up the ship does nothing to stop him from continuing his MO unabated.
