Robin Thicke "Dream World"
Moving Mountains- Two Steps from Hell
It is Groove Armada - I Won't Kneel: taken from the Black Light album; released as a single in 2009.
If it is the recent trailer where he had people putting their hands up in the air then it's Purple Haze by Groove Armada. I want to know what the latest one is which is more ballad like with lyrics like, "I could be you, you could be me, we could be one, we could be just fine..."
Blake Neely composes the music, but unknown the date of release
There are some music channels that show the latest hits. They are MTV, VMusic, and VH1. They feature the latest hits, latest music videos, upcoming gig guide and music festival line-ups.
There Isn't A Trailer You Probably Saw A Fan Made Trailer
the music for the 2nd or 3rd trailer is down the rabbit hole. by Murray gold.
La Roux - In For The Kill
Blake Neely's webpage is http://www.cowonthewall.com/projects/mentalist/ . He's the composer. I listened to his tracks from his page and Track 10 - Ep 103: Keys Trick sounds very very very much like the opening sequence. I believe that's it. However, his track titled I Believe - Theme from The Mentalist is there.
One can watch a trailer for the latest Harry Potter film on the latest Harry Potter film's website. One may also watch it on Youtube or Vimeo. Lastly, one may find some lesser known video sites to watch the trailer, but that would be needlessly effortful.
Track from Coldplay album Viva la Vida
It was original music writen by the Posthaste music library company
