The Cure were a leading alternative band in the late 1980s and early 1990s. They didn't really get a lot of mainstream success..... until this single in 1989 vaulted them into the Billboard Top 10.
It's not like they altered their style to get that hit. The song was someone morose-sounding, but its subject matter.... well, it was a love song. This wasn't a typical Cure song, because it was lyrically upbeat, and not trying to be clever - it was just a straightforward love song.
And, it's one of the most beautiful, lyrically simple songs ever written and performed.
