LOL... Am I like, the biggest Cure fan on Head-Fi? I'm 33 and I've been listening to The Cure for almost my entire life. Throughout late childhood, through adolescence, and my entire adult life. Without discovering The Cure, I wouldn't have found a whole bunch of other great and awesome bands and probably would still either be listening to crap or not care about music at all. Despite their long history and discography, I think they're still valid today as artists and I still think they make great music. But I'll shut up and let this video clip speak for itself:

Similar bands? I think The Cure is in a class of it's own because they're really indescribable... they have everything from delving you into deep despair to raising you to elated giddiness and everything in between. Having said that, I would say the most similar band would be Joy Division/New Order, but more of an artist development standpoint throughout the years. I would say maybe some Depeche Mode would be similar as well. Other bands that are popular with Cure fans (but not necessarily sounding like them) would be The Smiths, Echo and the Bunnymen, Siouxsie and the Banshees, and many others.
