The other night I went to go see the movie "ARGO" (very good btw) and I saw the preview for "Gangster Squad" (a period piece about the east coast mob in the 1940s). I am not a big fan of soundtracks that don't reflect the time and era of the movie but there was a super fresh Jay-Z song at the end of the preview. It's called 'Oh My God' and it's from the album "Kingdom Come". This song is perfect for when you want to feel like a total BadAss. The hook is intense and insane.
