Weezer's Variations on a Shaker Medley

Weezer's new song, "Greatest Man that Ever Lived" is now available on iTunes. I'm listening to it right now, and I really like it. There's definetly Weezer songs I like better (Buddy Holly) but I'll probably end up buying this. I love Variations on a Shaker Medley, and was kinda worried I wouldn't like this because of it, but I really do. The way it transitions reminds me of the really long songs off "American Idiot." (Which is a Green Day album, for those of you who are completely clueless.)
