Backing Track

For a long time i have been thinking of songs to use as my backing music for my trailer, should it be rock? should it be hip-hop? should it be rap? All these have been taken into account below i will attack some links of songs from the website Youtube. i was thinking about rap songs and hip-hop due to it will stereotype the trailer, this may not be a good thing but it will get the point across to the audience which is what i want.

Lil Jon - All the way crunkd up

This is the problem i have so many songs i like i cant pick one to use, i cant use parts off all of them either because then it will ruin the whole thing, the reason i cant is because it wont be fluent in the trailer and it could cause the audience to get confused thinking what has gone on here. The songs i have highlighted in green are the songs i think i will use i just need to narrow it down to one song. I need to use a gangster sounding track but the thing is they all fill that category.

Another massive point is that i need to write/ e-mail the producers to see if i am allowed to used their song for my trailer i will be doing this asap. hopefully i will be allowed to. if not then i need to find other song to use in my trailer that I'm allowed to use. i will be showing this e-mail on my block upon acceptance.
