I just bought this album, and I gotta say, if Rivers or anyone else has ever said that this album is the one they've been trying to make, I would believe them!
Ever since the Blue album, I've been looking for a consistently good Weezer album. With all the albums in between I've found it very hard to keep listening, but with this one, it's very hard to not stop.
Singles already include "Beverly Hills" and "We Are All on Drugs", which are pretty good songs. If they go for a third single, which they should, I'd recommend either "This Is Such A Pity", "The Perfect Situation", or the power ballad "My Best Friend."
But hey, this is a Weezer album, not Weezer songs surrounded by a couple of singles like the albums between Blue and this one. GO GET IT!
