Alright kiddies this is a hard one, I was unable to find out the info on the internets, so I'll ask you (thus finding out the info on the internets and making my previous statment a lie)

The Iron Man trailer features a song in the opening of the trailer, I later heard the song on the BBC show Top Gear, can anyone tell me what it is, its nagging me. 

Black Sabbath - Iron Man

Edit: I just remember thats in it. I am actually looking up the trailer now.

Edit 2: Hell Above Water - Curve is the actual answer 

Nope, thats in the later end of the trailer, this song is the very very beginning of the trailer.

No one is able to help me, dissappointing.......

Hell Above Water - Curve. Posted and edited so you see the update.

Thank you alpha you are the man!

Okay i have the name and stuff fo this piece of music, but i am pulling out my hair finding a place o download it... I'L EVEN PAY FOR IT!!!!

It's on iTunes, but not Amazon or iTunes plus. It does not look like it is available on their website either. Of course, there are always illegal methods of downloading it, but I am sure noone would ever recommend that...
