The DJ at Tony's birthday party is DJ AM (Adam Goldstein) who died after principal photography had wrapped, making this his last film project.

Album by Ramin Djawadi, OST to Iron Man (2008).

In the comic series Iron Man: Hypervelocity, Tony makes many references to an extensive playlist "heavily skewed" to '80s metal. If you don't have Metallica in that playlist, who even are you? This is a good track that perhaps compliments ACDC's Hell's Bell's featured as a prominent in the franchise.
