5) Tom Waits - Alice
4) Wilco - Yankee Hotel Foxtrot
3) Brian Wilson - Smile
2) The New Pornographers - Twin Cinema
1) The Arcade Fire - Funeral

Overall it's a pretty decent list, but there's several albums in there that I just don't agree with at all, including Franz Ferdinand, Devendra Banhart, Mars Volta, and, most of all, MIA.

Missing from the list? What about Bloc Party's Silent Alarm? The National's Alligator? The Hold Steady's Separation Sunday? The Delgados' Universal Audio?

I guess it's how you define "essential" - it might not necessarily mean "great" albums, but albums that have had an important impact on modern music in the last five years. If that's the standard, though, where's Clap Your Hands Say Yeah?
