The Cure set out to create the definitive, self-titled Cure album that basically summarizes their work over the past 20+ years. I own every album and have just about every B-side/rarity. This album really does feel like it spans various albums, with more of a focus on their later albums. Here's what I think the songs sound like, on a track-by-track basis.
LOST - a very stark, brooding, angry Cure song.
LABYRINTH - something from The Top/The Snakepit. It has that psychedelic drug-induced sound to it.
BEFORE THREE - sounds like a Wish B-side. Kind of pop, kind of depressing. Heavy guitar sound.
THE END OF THE WORLD - a goofy Wild Mood Swings song, like The 13th or something. Gets kind of weird in the middle, but mostly poppy.
ANNIVERSARY - A classic, dreamy Disintegration-era song.
US OR THEM - An angry, edgy Kiss Me Kiss Me Kiss Me type of song.
ALT.END - The intro sounds a lot like In Your House from Seventeen Seconds.
(I DON'T KNOW WHAT'S GOING) ON - I don't know what to think of this song.
TAKING OFF - Could be a Wild Mood Swings B-side. Reminds me a lot of A Pink Dream.
NEVER - Simple, early Cure Three Imaginary Boys type of guitar song.
THE PROMISE - Harsh, feedback-heavy, swirly Wish-era guitar song. Sounds a bit like The Kiss.
Get the U.K. version on CD if you can. With that and the End of the World single you get all 15 songs from the double LP album instead of just the lame 11 song U.S. set. Overall, I really like this album. Like all good Cure albums, you have to listen to it over and over to really get a good feel for the album.
