I bought it, and have listened to 8-9 tracks. It sounds very old school, much more so than their last album. I don't agree that it has better beats than their last album, though. The songs seem shorter and more focused. There's more foul language than on previous releases, it seems. There's at least one track that's political in nature, which is something I don't remember hearing on other albums (there's something about "we got a president we didn't elect) in one of the songs.
If you like the Beastie Boys, pick it up. I don't think you'll be disappointed.
