My Nicki Minaj Compilation question.

So, I found this 9 hour video of most Nicki Minaj songs. Some songs are played twice in the video. I want to edit the songs--that play a second time--out of the video. I've been editing using Movie Maker; I tried trimming out the songs myself but couldn't do it because the video was so long that it couldn't accurately pinpoint where I wanted to trim the video.

Can I enlist the help of someone who will edit out the songs that play a second time?

 

Here are SOME of the songs that play twice:

1) "Handstand"
2) "Girlfriend"
3) "Blow Ya Mind"
4) "Your Love"
5) "Keys Under Palm Trees"
6) "Nicki Minaj Speaks #1"

 

Is anyone here good at video editing?

So, there's a Nicki Minaj video on Youtube that's a collection of Nicki songs. I noticed that there are some songs that repeat in the video, and I want those songs edited out... I have the times of the repeating songs.
In place of the deleted songs, I want to put in some cool Nicki songs.
I need someone who's great at video editing to take out the repeating songs.

Anyone wanna help me out?
