[quote name='karsh']I need to start learning just cause a song is in the trailer for a movie, doesn't mean it's on the soundtrack. I thought the song from Return of the King's trailer, Lux Aernata, was gonna be on the soundtrack, but it wasn't. Now, I thought the song from all the Sin City trailers would be on the soundtrack, but apparently it isn't.[/QUOTE]
Yaeh a lot of movie studios have started to do that where they'll have trailers with a great song which you'll think will be on the soundtrack but once you get it, you see that it's not there. I think it was documented last year as I remember reading an article on it. I know that the song that was in the trailer for Punisher from last year which seemed awesome wasn't on the soundtrack. Still, I think the Sin City soundtrack should be good. Robert Rodriguez puts together great music that fits with his movies just like Tarentino. One of my favorite soundtracks is the Kill Bill volume 1 OST. I need to pick up the second sometime soon.
