This music is additictive to listen to. This is serius music for, well, serious party rocking. The only reason I give it 4 stare rather than 5 is that, while there are a few excellent tracks on this album, there are a few that don't quite stack up. To be expected with most full albums, but it does not take away from the fun yoy will have with it. I highly recommend searching out the music videos for such songs as "Party Rock Anthem" and "Sexy And I Know It". It will definately make you appreciate the tracks more. Classic stuff.
