I work with college kids. They don't understand the absolute obsession a lot of old people have with The Dark Side of the Moon. For the longest time I couldn't figure out why. It's like the perfect album.
And that's what finally dawned on me. It's the perfect album. The songs are really good individually, but the album is a masterpiece when played how it was originally meant to be played. The pauses and the transitions and the background noise of the player all brilliantly factor into the album.
And the 20 year olds I interact with mostly listen to individual songs instead of albums.
It's such a subtle difference that most people don't even recognize it.
